Super Flexible File Synchronizer

Version History

New Features In Version 5 (now available for Windows)

Support for Microsoft Azure Storage and Google Docs
You can now synchronize with Microsoft Azure Storage and Google Docs! Azure Storage is quite straightforward and even retains the files' original timestamps. Google Docs has limitations and peculiarities, and it is described here.

Chaining profiles
You can now use RUN PROFILE in Job->Execute before/after to chain profiles. Additional enhancements are documented on the Execute before/after dialog.

Detection of FTP Server Timezones
The timezones of FTP and other Internet servers can now be auto-detected, fixing some common timestamp-related problems.

Various
Partial File Updating, Mode 2 is now supported with SSH. A new setting "Verify Copied Files" is now available. Where possible, it uses server-generated MD5 checksums. The ExtremeSync Remote Service can now generate such checksums, as well as some FTP servers and Amazon S3. See the settings on the tab sheet "Files" as well as "Comparison->More". Binary Comparison is now supported for all protocols and also uses MD5 where possible.

Synthetic Backup (=Differential Versioning)
You can now combine Partial File Updating with Versioning, Zipping and Encryption and use it with any backup storage location, including FTP and other Internet Protocols.

Checkbox to choose:
- tab sheet Versioning->Synthetic Backups: "Use Synthetic Backups"
The following dependent options are then checked automatically:
- tab sheet Special: "Partial File Updating" (without Remote Service)
- tab sheet Zipping: "Zip Each File Individually"
- tab sheet Versioning: "Filename Encoding"
 
All incremental versions must be kept in the same folder.
 
Be sure to keep all zip files on the destination as they may all be needed to reassemble the file upon restore. However, the number of older incremental parts that need to remain on the backup storage can be limited thru the new "Checkpoint" feature. You will find its settings on the new tab sheet Versioning->Synthetic Backup:
 

A checkpoint is an incremental backup just like the daily backups. However, it is a little larger because it includes the changed blocks of a longer period of time, so that many preceding incrementals become unnecessary.
 
Any older version can be restored by choosing the desired target date in the Restore Wizard, or by right-clicking the file in the Sync Preview and choosing the desired version. The option "Keep multiple files" is implied and does not need to be checked. It cannot be used to limit the number of older versions. However, if this option is specified on the Versioning tab sheet, it will be used as a minimum number of versions to keep even if the Checkpoints feature would allow to keep fewer versions.
 
A restore of the synthetic backup files can be done independently from the original job, to any destination. No database is needed for the restore - just the files.
 
Block-level copying is applied to files which are at least 400,000 bytes in size. The granularity of the differential backup is determined dynamically for each file, based on its size. The smallest block size used will be 2048 bytes.
 
Each partial backup includes an MD5 checksum for each file, so that restored files can be verified to be 100% correct. You can see this in the file MD5.TXT that the partial zips contain.
 
The Zip file sizes can now be limited too so that large files can be split (only in conjunction with Partial File Updating). The transfer can be stopped any time and zip parts already uploaded won't be lost.
 
Embedded SQL Database
An embedded SQL Database Server is now being used for the reference databases: Firebird on Windows, and SQLite3 on Mac. The server does not need any configuration. It is used for SmartTracking, for the Destination Cache and for storing the checksums for Partial File Updating. On Mac, the SQL engine is also used for the configuration file. Older INI files are automatically converted. The SQL server communicates directly via its library file, so there is no TCP/IP or other interprocess communication that would be seen by Firewalls. Embedded SQL runs as part of the Superflexible or ExtremeSync processes.

The new database engines are a great improvement over the old database structure, especially in terms of reliability and scalability. It can store an unlimited number of file entries and other data without becoming much slower. A separate database file is created for each job (like before). Old databases are automatically converted.
 
Parallel processing of real-time jobs
Profiles that use real-time synchronization can now be processed simultaneously, and the copying can happen in parallel. In addition, if several profiles monitor the same source folder, or various subfolders of the same source folder, then the monitoring is pooled in order to minimize resource and CPU usage. Thus it now becomes possible to have over 100 real-time profiles all running on one machine.

 

What Was New In Version 4

Version 4 is available on the Downloads page. The version 4 update is a free for purchases after Oct 1st, 2007, but you will most likely need a new registration code. Older licenses will be eligible for an upgrade at 50% of the regular price.
 
To obtain your new registration code or see your upgrading options, please install version 4 and click on the "Show Upgrading Options" button on the Ordering tab sheet in the software.
 
Version 4 can be installed over an existing installation and the profiles will be retained. You may want to make a copy of your SuperFlexibleSynchronizerPRO.ini file in case you need to switch back to version 3 (even though most profiles will port back without a problem).

A few smaller improvements.

5.48
Restoring files with filename encoding from a local drive now uses the encoded timestamp rather than the backup file's timestamp (as it already did via FTP etc.).
When you have a job that uses "Move Files To Destination" then you can click on the Configure button and choose the new checkmark "Move by Copying then Deleting".
New checkmark on the tab sheet Files->More: "And Compare File Details (Again)" (during the copying phase). This allows to speed up copying by choosing "Do not scan destination" but still copy only files that need it.
On the tab sheet "Waiting & Retrying", the checkmark "Avoid re-run due to locked files" will now also ignore files which are no longer there because they have been removed by a user between the file list building and the copying.
Macintosh only: adds identification criteria for mounted drives on the dialog Job->Mount Volumes to avoid duplicate mounting. Also prevents two simultaneous jobs from mounting the same volume at the same time.

5.47
Macintosh only: speeds up the database by factor 8.

5.46a
Fixes an error message that could occur when Partial File Updating is used with a Speed Limit.

5.46
Improves handling of locked or unreadable files when adding them to ZIP Packages containing many files.

5.43
Real-time can now be used with variable such as $WEEKDAY and will automatically monitor the new folders after midnight.
New setting for Partial File Updating when used with Remote Service: "Request only one file at a time". This reduces the load on the server since checksumming and copying will not occur at the same time.
Windows only: you can now disable the pooling of network monitors on the Advanced tab sheet of the Program Settings dialog.
Windows only: adds a Cache Control setting for Microsoft Azure Storage uploads.
Mac only: fixes a problem with real-time sync not being able to process subfolders that contain non-ASCII characters.
Mac only: fixes a problem where real-time sync would not process moved folders.

5.42
Windows only: real-time improvements.
Windows only: you can now specify the cache control expiration period for uploads to Microsoft Azure Storage. Azure uploads now use the appropriate MIME type based on the filename extension.

5.41a
Windows only: if making a network connection fails due to existing connections that conflict, the program will now scan them all and disconnect the conflicting ones (if the appropriate checkmark is set on the Network Connections dialog).

5.43
Fixes a problem where the program would end up in an infinite retrying loop if the source file became bigger while being copied.

5.41
Windows only: important improvements and bug fixes with Real Time Synchronization.
New variables added, see docprofi.htm
Fixes a bug with the option "Verify Sync Statistics After Completion", where the statistics were calculated but not logged.

Mac only: fixes folder exclusion masks containing diacritical marks.
Mac only: fixes copying totals which were incorrectly summed up with only 32 bits rather than 64 bits.
Mac only: on Snow Leopard and above, the program now uses Apple's new math where 1GB = 1000 MB, etc.

5.40
Windows only: improved copying of NTFS security settings. Now works better with local drives as destination. New setting: Take Administrative Ownership on the File Access tab sheet.

5.36c
Azure storage can now upload files larger than 64 MB and uses SSL.
Fixes a WebDAV problem with URL encoding of the @ character in file names.
Fixes a WebDAV probem where some servers don't expect a trailing slash with the MKCOL request.

5.36b
Windows only: fixes an issue that could leave multiple unnecessary, idle ExtremeSyncService.exe processes running.
Fixes various issues in resuming failed ZIP Package uploads in additional profile runs.
Fixes another possible cause for a "Failed Path" error when using the Destination Cache with SFTP/SSH.

5.36a
Windows only: contains a few optimizations and a new safety feature for Real Time mode that makes sure that SmartTracking settings are not applied to newly created folders, so they can't be mistaken for having been deleted on the other side.

5.36
A date/time filter such as "File Age: over 1 minute" can now be used with Real Time Synchronization in order to delay the copying. Between 1 and 60 minutes are acceptable. Higher values will lead to new files not being copied at all.
Fixes an issue where Partial File Updating would need two runs if the file size has become smaller. The first run would update the blocks and the second run would truncate the file. This bug was new in 5.35.

5.35e
Fixes a "Failed Paths" problem that could occur with certain Destination Cache settings.

5.35d
Fixes a bug in Partial File Updating that could cause files to be copied entirely again rather than partially.
Fixes a bug that could cause MD5 verifications to fail.

5.35c
Mac only: if the config file cannot be created in /Library/Preferences, it will now automatically be created in the user's Preferences folder. This also fixes the error message with "Global Checkpoint ME1" that some users have seen.

5.35b
Fixes an access violation error since version 5.35 caused by Partial Updating from right to left with Remote Service for checksums and Fast Mode off.

5.35a
Windows only: fixes an error message about symbolic links caused by NTFS junction points. The error was introduced in version 5.35.

5.35
The main program no longer minimizes to the system tray. It now minimizes as any other application. The tray icon is now used only by the Background Scheduler.
Partial File Updating now uses very little memory even for multiple-GB size files.
Resuming the initial upload via SSH with Partial File Updating now calculates the checksums for the part that was already uploaded. Previously, incorrect checksums were stored in the database for that part.
SSH upload speed with Partial File Updating has been improved by combining several blocks into one for uploading.
If FTP retries are set to a high value, trying to determine the existence of a folder no longer uses that value (only 2 retries) in order to avoid unnecessary delays and retries.
Real-Time Synchronization now recursively looks into any new folders created in order to avoid files from being lost when a folder is moved.
Progress information is now sent to the GUI and the scheduler by background jobs while waiting for an external command to complete.
Since rc2:
Some FTP errors could lead to a subfolder being considered empty, rather than producing an error message. These errors are no longer suppressed and the folders are now correctly considered inaccessible rather than empty.
On Amazon S3, the folder listing would come out incomplete if folders starting with a space existed at the top level of the bucket. This was fixed.
Remote Listings are now zipped by the new ExtremeSync Remote Service.
Since rc3:
Fixes a possible communication problem between main program and ExtremeSync Remote Service. Since rc4:
ExtremeSync Remote Service now uses very little memory for creating checksums for Partial File Updating even for multiple-GB size files.
rc4 also fixes the remote unzipping feature which was broken in rc3.
rc5: now even stricter about inaccessible folders (mostly FTP, WebDAV etc.) which previous versions may have considered empty without showing an error. This may cause existing profiles to show errors ("FAILED PATHS") which were previously ignored.
Buuld 182 fixes a problem where this FAILED PATH message could appear in real-time mode when a new folder was created on one side and did not exist on the other yet.

5.32b
Windows only: fixes the new ExtremeVSS not working in background jobs running in a separate thread.

5.32a
Adds "Open Folder" menu item to the menu in Sync Preview.
Windows only: fixes the new ExtremeVSS not working on some systems.
Mac only: removes a 4GB size limitation for zipping files.

5.32
Improves detection of copying direction if incomplete files exist on one side due to another user uploading a file.
Windows only: adds ExtremeVSS Service which enables any user to take advantage of the Volume Shadowing even if UAC is on. This makes it easier to copy locked files such as Outlook PST files when Outlook is running.

5.31
Google Docs improvements: can now handle files being in several folders and uploads PDF files with the correct file type and icon.
Bug fixes concerning the Exact Mirror options "Removal Of Deselected Items From Destination".

5.30f (Mac only)
Fixes the WebDAV module being broken in 5.30d.

5.30d
Removes a bogus FTP error message that was added for testing purposes only.

5.30c
Fixes a filename parsing error that could occur with some WebDAV servers that use an encoding like & rather than &.

5.30b
Fixes "access denied" error when using Amazon S3 with lower case bucket names.

5.30a
Integrity Check improvements. If you used the Integrity Check before, please clean your TEMP folder.
"Check For Update" was broken in 5.30 - fixed.

5.30
Windows only: adds a second WebDAV library with new SSL code as an alternative to Windows SSL. The new library also supports the WebDAV feature "Expect: 100-continue". This can be chosen on the second tab sheet and it is useful to optimize communication when Basic Authentication is not used.
Recognizes FreeSSHD and then avoids setting file attributes in order to prevent the server from crashing.
Fixes a bug occasionally causing folders not to be deleted although they should be.
Windows only: fixes a problem where the database engine could not open a database when the option "Run As User" was used.
Windows only: fixes excessive CPU usage when uploading via SSH/SFTP. This fix can also improve the upload speed.
Fixes an incompatibility between Encryption and Auto-Resume. Encryted files are always different due to random encryption seeding and cannot be resumed on a new profile run. It is recommended to use the Verify Integrity feature on jobs that combined these features. The new version never resumes files from previous profile runs that use the Encryption feature.

5.21c (Mac only)
Fixes a bug where the port number for Internet Protocols would be reset to the default each time you open the Internet dialog.

5.21b
The new automatic recursive FTP listing will now detect truncated listings from some FTP servers and fall back to non-recursive listing.
The algorithm that computes the year of the timestamp for recent files where the FTP server does not report the year has been improved.

5.21a
Fixes a database error message that could appear in the log files under some circumstances.

5.21
The Internet dialog now contains additional information on how to obtain the Azure Account ID and makes sure that Container name and Account ID are not mistaken for full URLs.
The Monitoring Tool now gives detailed error messages if the remote editing of profiles does not work (for example because it is not enabled).
A new version of the ExtremeSync Remote Service fixes an occasional problem preventing checksums for partial file updating from being generated.
Various additional bug fixes.

5.20c
Fixes an access violation bug introduced in 5.20a which could happen if the file masks or exclusions were longer than 255 characters.

5.20b
Fixes an incompatibility with some FTP servers caused by the new automatic recursive listing command introduced in 5.20.

5.20a
Fixes UTF-8 decoding of HTTP files.
Fixes MBCS profile names (such as Chinese on Chinese computers). Profile names are not Unicode.

5.20
FTP now uses the recursive listing command LIST -alR by default in order to speed up building the file listing.
The field for the versioning folder on the tab sheet Versioning can now accept paths up to 129 characters long.
A compatibility issue with Serv-U SSH server preventing upload resuming was fixed.
The installer now includes ib_util.dll so that Firebird won't complain about it in firebird.log any more.
Fixes a problem that could cause unnecessary copying of older files caused by the handling the timestamps for which the FTP server only reports the date, not the time of day.
Fixes an occasional access violation preventing a system shutdown after shutdown jobs have been executed.
Various additional bug fixes.

5.19a
Fixes a problem where the scheduler may prevent a Windows shutdown.
Fixes a problem in Real Time mode that could occur when a folder is deleted. In that case, on the other side, the folder may have been moved into the Folder for deleted files as specified, but files in it might have been deleted permanently.

5.19
Reinstates the "right-click select" functionality in the Profile Overview and the Sync Preview.
Fixes the "Case Sensitivity: Adjust At Destination" function which was not working in some cases.
Fixes an "Integer Overflow" error which could occur if copying of a large file took a very long time.
Various additional improvements.

5.18b
Auto-Detection of the timezone for Internet Servers (such as FTP) is now on by default.
Fixes a bogus 217 error code when copying ZIP Packages that aren't zipped directly to the destination.
The "Copy Only X Files" setting is now more precise.

5.18a
Fixes wrong text where it would say "added on right side" which actually meant "added on left side".
Fixes an FTP problem with library 1 that could cause connection failures.
Fixes a combination of options which did not work correctly: "Keep multiple backup versions" without "Filename Encoding" but with "Zip Each File Individually" (also without "Partial File Updating").

5.18
Fixes a few FTP related issues.
Will no longer re-use pre-existing remote MD5 checksum files if the option "Always copy the files, even if timestamp unchanged" is chosen.

5.17a
Scrollbars are now proportional.
Remote Service updated to fix a possible bug when creating multiple MD5 checksums in parallel and some files are over 16GB (the checksum creation might fail).

5.17
Fixes a few FTP and SSH related issues.

5.16a
Adds timezone detection to SSH because some servers don't use UTC (world times).
Automatically uses UTF-8 (Unicode) encoding for FTP servers that officially support it in their features list (FEAT).
Restores Wizard Mode graphics missing in 5.16.

v5.16
Adds a checkbox to use the Creation Date for time-based filters rather than the Last Modified date.
Is now aware that Microsoft FTP Service 7 supports MDTM to set the last modified timestamps of files.
Improved reliability after SSH or FTP transmission errors by enforced re-connection.
Contains an updated version of the SSH library.

v5.15
Fixes partial file updating occasionally copying the complete file although it's not needed.
Fixes a problem in 5.14a causing the INI file to be switched and the Prefs selection to be grayed out on some systems.

v5.14a
The Profile Overview is now automatically updated when restoring the program from the system tray.
Fixes the new Exact Mirror settings (delete non-matching/deselected items) not being hooked up in Wizard Mode.

v5.14
Adds the ability to ask for password if decryption password in profile is incorrect.
Improved timezone detection compatibility with some FTP servers.
Can upload files to Google Docs up to 1GB.
Adds file size checking after SSH uploads.

v5.13
Fixes a few issues.

v5.12
Adds checkbox on Files->Deletions: "Never Delete Any Files (Only Folders)". This can be used to just mirror the complete folder structure without any files if you also choose "Never replace any files" and "Don't add any files" on Files->More as well as "Create Empty Folders" on Folders.
Now compatible with Serv-U recursive listings (choose LIST -alR as FTP listing command).
Fixes an issue introduced recently that could cause empty Amazon S3 buckets to be repeatedly queried for each folder present on the other side.

v5.11
Fixes a possible problem with the auto-detection of FTP server timezones when a relative path is specified in the profile (a folder not starting with a slash on the Internet dialog).

v5.10b
Fixes a bug introduced in 5.10 that could cause a slow-down and occasional error messages when zipping many files in parallel and uploading them individually.

v5.10a
Fixes a bug introduced in 5.10 that could cause FTP connectivity problems due to Passive and Active mode being exchanged.

v5.10
Interrupted ZIP Package uploads will now always be resumed the next time the profile is run - even if the ZIP Package is split. Previously this feature was only partially implemented.
Fixes a problem where the application would not load on some computers (an issue caused by some printer drivers).
In real-time mode, if a file is renamed and the original filename is filtered, it will now copy the file if the new filename is not filtered.

v5.09a
Fixes an issue with several real-time jobs monitoring the same folders where some of them might stop the activity.
The destination cache will now realize that the database is incomplete if only real-time runs have been done so far (rather than a full sync).

v5.09
The "verify sync statistics" feature will now list "differing files", if any.

Fixes a problem in version 4.33(a) where SSH profiles would not work when run in parallel in the background.

v4.33a:
Fixes a problem in version 4.33 where emails would always be sent, even if nothing was done or no error occurred.

v4.33 (Windows only):
Running several profiles in parallel has been improved substantially in terms of performance and reliability. The new version will also run profiles that use Internet Protocols in parallel threads rather than a separate process for each job. The status display "No contact for ..." should no longer appear.
If a profile is repeated due to an error, only one email is sent combining the information for all profile runs (see the Access & Retries tab sheet in the profile).

v4.32:
WebDAV with https now works correctly with Proxy servers.
Fixes the "needed" storage space mentioned in log files.
Adds option to include a list of copied files and other actions in the email notification text.
Adds option to send the notification emails to both the global email recipients and those specified on the "Override Email Settings" dialog in each profile.
Mac: fixes display of Chinese characters.

v4.31:
Volume Shadowing can now be used on 64-bit Windows.

v4.30a:
Adds the capability to import several INI files at once.
Fixes a scheduler bug that could cause profiles not being run.

v4.30:
The ExtremeSync Remote Service can now be used to build the file list on the server and transmit it in one file. This can greatly speed up building the file list. The new Remote Service and Control Panel must be installed on the remote machine. On the local machine, edit the profile in Advanced Mode, go to the Special category and choose the new checkboxes "Left side listing uses Remote Service" and/ or "Right side listing uses Remote Service".
Also fixes the Speed Limit option which was not working in all cases in versions 4.2x.

4.22a (Mac only):
Adds support for executing a script or application before and/or after a profile. See the Job category in each profile.

4.22(Mac only):
The first official Macintosh release.

v4.21b:
Fixes an "invalid floating point operation" error which could occur under some circumstances when no files were to be copied.
The WebDAV module now interprets BST as British Summer Time.

v4.21a:
Fixes downloading files over 2GB from an SSH server.
Fixes timestamp synchronization with some WebDAV servers.
Fixes upload resuming with FTP library #3.

v4.21:
Fixes email notifications which were missing in 4.20 when profiles were run in parallel in the background.
Volume shadowing is now triggered by locked files being uploaded using an Internet Protocol even if they are not zipped.
Other improvements and bug fixes.

v4.20:
Copy several files simultaneously. The number of parallel copied files is specified on the Files tab sheet in the profiles.
Import and Export Selected Profiles
SmartTracking can now delete files directly and no longer forces you to use a folder for deleted files.
SSH authentication made more failsafe. New Advanced SSH Settings dialog available on the Security tab sheet of the Internet dialog.
Details about conflicts are now written to the log file.
WebDAV automatically adjusts for some sites, for example it now works with the box.net service without changing any settings.
SmartTracking no longer deletes folders when the last file has been deleted.
Added new /MASK= command line parameter.
New setting on the Files->More tab sheet: "Preserve Last Access Time Stamp On Source".
Other improvements and bug fixes.

v4.14b:
Fixes setting timestamps via FTP which has been broken in the last few builds.
Folder deletion via WebDAV should now work with all WebDAV servers.
The Remote Service's unzip function is now Unicode-enabled.

v4.14a:
Fixes a possible error message when running more than one profile via command line, as well as the tray icon missing when running profile via command line.

v4.14:
Fixes the tray icon occasionally missing when using the service scheduler.

Fixes the "target date for restore" being ignored by the Restore Wizard.

Minor UI improvements.

v4.13d:
First Spanish Release.

Fixed an error when the service is stopped while monitoring the network (Schedule->Monitoring).

v4.13c:
Added a button to the toolbar that appears when the INI file is read-only. It invokes File->Enable Editing, which has been improved.

Coarser progress reporting when copying with Windows API copying function.

Fixed an AV when downloading with Partial File Updating, when using the Remote Service to generate checksums.

v4.13b:
Fixes new bug in 4.13a on systems without volume shadowing: unnecessary message about a VSS error code, plus service won't start.

On the welcome screen, the scheduler button is now labeled according to the current scheduler state (running or not running).

v4.13a:
Fixed some dialogs on Windows with large system fonts.

Fixed an AV error message that could occur with the /RUN= option (not /RUNX=). Added $MAINUSERNAME and $MAINUSERPROFILE which refer to the user that started the program even if a profile uses "Run As User..." to run as a different user.

v4.13:
Fixed a problem where zipping could fail occasionally when profiles were run in parallel and a profile completed while another profile was zipping a file.

Fixed a problem where Partial File Updating would not create a database unless some other database-related setting was used (such as Cache Destination File List). Existing databases were updated fine, but if a database did not exist for a profile, Partial File Updating would not work.

v4.12d:
Fixed the Auto-Resume feature when copying directly from FTP to FTP.

v4.12c:
Fixed the setting "Folder Masks" which sometimes did not stick.

v4.12b:
Fixed the setting "Run monthly". More detailed error logging in case zipping fails.

v4.12a:
File shares without security descriptor are now processed (previously they were being ignored).

Since v4.12, FTP will now automatically try both passive and active mode if it can't get a directory listing. In v4.12a, this mechanism was fine-tuned so that the new attempts are not triggered by empty directories.

v4.12:
Fixes a problem where the database would cut off very long paths when Partial File Updating was used.

Some improvements related to mirroring file shares.

v4.11:
Fixes occasional error messages when the scheduler runs as a service 24/7 without interruption. The service will now automatically restart itself after 24 hours, or after 50 jobs have run. This is a matter of 1-2 seconds and will not have any side effects.

Adds replacement of disallowed characters on the Internet Protocol Settings dialog, tab sheet Advanced. Currently, there is only one supported disallowed character, which is the colon. Some FTP servers may store filenames with colons. These can be replaced with the division sign when downloading.

Fixes FTP problems with the special y character with two points, as in the name Queensrÿche.

Zipping and encryption now works with long paths (>252 characters).

Fixes additional minor issues.

v4.10:
Adds new features to handle a special problem with Sharepoint synchronization. When Microsoft Office documents are copied to a Sharepoint folder, the server may add some tags to the file, thereby changing its file size. Two alternative solutions are available to handle this situation:

a) copy modified files back immediately
On the Special tab sheet, you can use the new setting "If the Destination Machine Modifies Received Files, Changing Their Sizes Upon Reception, Then Copy Such Updated Files Back", or

b) use SmartTracking
on SmartTracking->Options, check "Detect Unchanged Files" for the SharePoint side and check "Also Ignore File Sizes Being Modified By Server Immediately After Upload".

The two options can be combined.

Additional changes:
improved handling of SSH errors with error messages rather than numbers and bug fixes.

v4.04-4.09:
- various issues addressed

v4.03:
- adds CPU selection in the Program Settings

v4.01/4.02:
