FreeFileSync Forum

Thank you!

This is a synchronization tool, not cp/rsync/rclone...

Just fork [URL] and let us know about any meaningful contributions.

Those are not included in the source for the application. They're not strictly required for building the application from these generated C++ files. It would be cool to see them, h…

Eh, WinGet and package managers in general are pretty great. Being able to load/update with software-agnostic CLI is awesome. Couple problems with FFS being on WinGet though: - Sil…

+1 Why one of the most important options is hidden from the GUI is beyond me. To reduce the influence of any cache on the receiving side the verification process should not run bet…

Would it be possible for FreeFileSync to remember the size of the Synchronization Settings window? I use long paths, and that window is so narrow it results in wrapping, which make…

You need to use the "Mirror" variant: "Update" is not an option of it, is a totally different variant.

so I can donate

Please implement a custom secure copy setting for tasks, rather than a general one in the settings. For example, to sync with "S3" storage, you need to disable this option to preve…

Thank you for the explanation. I'm basically wanting to do an incremental backup starting from a specific date. The "This Month" Time Span filter will be fine for my requirement. T…

You're right; converting it to .txt must have changed the encoding. Strangely enough, both versions run without a hitch on my computer—UTF-8-BOM is the correct encoding.

Anyone else that wants the time estimation to be improved? I guess we have a pretty good strategy worked out in this thread.

In FFS the comparison progress is shown docked at the top of the FFS-window. I really love this, because no extra window is shown. The synchronization progress is a separate window…

Yes that's what I discovered too. That is precisely the feature that I was suggesting should be added - and I can't imagine it should be too complicated. I t would be very useful, …

"\999" is going to be a subset of "*\999" and produces no difference in your limited dataset. Just because: 111*: \111*: *\111*: all end up with the same result in your tests, does…

I suppose you refer to the "time-stamp" naming convention used in Versioning. For the "time-stamp [File]" option I don't think you can (unless you change the program source and com…

Thank you, I'll get on with it.

And so, FFS that freeze is merely the visible symptom of a much more serious problem and external to FFS, and so irresolvable. Get it, thanks.

version 14.9: [Code]

Worked fine for me, using your files provided, running 14.9 Donation Edition as well. Is this Toshiba disk attached via USB? Or is it some cloud/network device? Copying the files m…

I had to redo the syncing of some folders. The regular syncing process wasn't hard, just following YouTube tutorials. However, RealTimeSync wasn't as easy. I had it set up before, …

Thank you for your patience. For the sake of completeness, having said that, if you wish, we can close: The parent folder contains the file that stores all the passwords saved in t…

I can get it to mirrow and compare. That's not the issue. It starts getting wonky when tyring to tie in RealTimeSync. I have found Cobian and I am happy with that. Much simpler to …

Just noting that cloudflare spit out some... message, the first number of times when I went to view this site this morning. (Don't know what changed, to let me in?)

If I try to synchronize the directory with Google Drive (donated version supports Google API) i got in trouble with some ziped/7zupped files. I got message [Quote] Similar problem …

Please enhance the "Statistics" display to add the _net_ space change on the target disk. It is helpful to know how many files/items and bytes will be copied, but when there are al…

Please enhance the "Find" functionality in the Compare pane to show the number of hits from the find. If the display can also be made to track where the user is in the hit list (x/…

Please enhance the context (right-click) menu for the "Configuration" pane values to add an option which displays the date and time for the most recent sync, and which provides a l…

Thanks.. I had not noticed that.

Thank you much for the explanation. That would seem the most functional premise and pleased to hear that's how FFS handles it. I don't see any ability for Kudo points, likes etc on…

Ups, you are right. I messed up the translation. Of course the error message says: "... Please reinstall FreeFileSync." [Attachment]

Here are some (including some dups). . [Zenju, 2026-4-07: removed. Please don't share them] I just wonder whose birthday is on 6/20 ?

I have a couple requests/suggestions to make syncing much more efficient in some situations, when using the "Copy DACL, SACL, Owner, Group" option: First: Using the recommended "fa…

The batch config will display them if you run the comparison manually in FFS. Only if you run the batch config via command line will it auto run and close

Hello, I would like to set a time limit for syncing, too. Of course FFS would have to check the time only between syncing files and stop gracefully when the file is finished and th…

No, it is not a scheduled task, I just want to check the folder for changes and then actualize the target folder,

Hi, I also sync to Nas. 1. Have you tried mapping a drive letter to nas share? 2. I prefer to mount nas using rclone. You can try that too.

This has been fixed in the next FreeFileSync 14.9.

Hi, I put together some notes regarding your situation. They describe an easy way to split your large backup between two smaller physical disk drives. [URL]

Yes, so, assuming that you use FreeFileSync on these files, it proves that the File Size comparison setting uses Folder Name/File Name/File Size as the comparison value.

Well my issue is for the backup of the one drive is spread among 5 drives that I can only connect one or two to the pc at a time. all my other drives have the exact same drive as a…

The limitation of the solution of both therube and ertank is that it only works if no other/further FFS instances are active, running syncs on other, non-related left-right pairs. …

Agreed 100%. It is just a matter of terminology. It was my mistake. The software is great. However, I still think that a warning would be of benefit. That would be relatively easy …

Here is some information that's together regarding the use of your own SMTP server. You can't remove the built-in server but you can add your own. [URL]

I have not used it, but I googled it and found this: [URL]. Icons in .exe files are just a resource, and I would expect you can swap them around with a tool that sounds like this. …

Windows 10 Pro x64. FFS v14.8, "normal" version - not paid for version. On my system I run as an limited user (e.g. user "Tom") and have to "elevate" to an alternative, admin capab…

Ill look into these

Wait. Found it.

I remember seeing this request before. One of the issues this causes is that two files may be flagged as different sizes even though the size column is equal (eg. 1KB vs 1KB). This…
