FreeFileSync Forum

Anything on Flatpak that is not Verified must be treated as a toxic cancer that will blow apart your system. There is absolutely no way of knowing what it contains. For the FFS one…

I'm a new user of FreeFileSync (having given up trying to keep Windows 11 File History working reliably). I use it to back up a number of drivers and folders on my PC to a NAS driv…

My main sync job has 80k+ files that it compare and does mirror for. Maybe it is relevant. I do sync for my browsers and mail client profiles and they have thousands of small files…

Yes. I wanted to add that to my submitted question, but there is no edit option. Yes, H: is the DVD drive.

[Quote] Nothing has changed in 14.13 that could explain this. In any case, to get rid of "Error code 0x1c0" FreeFileSync needs to run with admin rights on Windows 11.

[Quote] Zenju at least has the means to investigate the issue and possibly even come up with a workaround. Or at least confirm that it's on their radar for things to be looked at.

Yes. You should be able to combine the net view and the running of FreeFileSync in one batch file.

Ok I figure out a sort-of-kind-of partial fix. It's a 2 step process: On the windows machine I renamed the directory "m" to "ma". Then I renamed it to "M". You can't rename directl…

[Image]Hi A year ago I bought a FreeFileSync Business version to my Lenovo Yoga 7. Now I have a new computer, a HP ZBook, so today I uninstalled FreeFileSync on my Yoga 7. But, the…

When I compare the files I get a list of differences. In the action column I can click and set the update direction, e.g. to left, to right, delete, whatever is appropriate. This w…

Thank you for the fast response and help!

I have a USB drive connected to my Linksys router mapped as D: and since moving to a new laptop any changes made to directories monitored by RealTimeSync on that drive are only det…

when I click on the Compare at the top I start getting messages like this. for the 56 files that will not copy. I know they are on the windows pc.. [Attachment]

No help here but this may become more urgent as Ubuntu 26.* no longer provides X.org support. log error: Authorization required, but no authorization protocol specified Authorizati…

Whenever I start a compare, the Software Crashes with message: [Code] The issue occures only when using Version 14.12. I downgraded to 14.11 as that version works fine. I use a Lin…

I considered WiBoBnl's second question as a separate question, unrelated to his first question on time-span syntax. > but does that (the time-span) get saved in .ffs_gui or .ffs_ba…

See if anything here applies, [URL] ? (And if so, if the beta fixes things.)

From the log: [Quote] I'm running FFS 14.12 [Donation Edition] as administrator on Win10, and have the setting on to include symbolic links as links. Copying regular files into the…

I appreciate you trying to help me with what is there, but this was indeed a feature request. It would appear that once we have wandered into macro territory, it both speaks loudly…

[Quote] (in home use context, well maybe both) On virtual systems BIOS passthrough should keep this easy and static(hypervisors make this programmable field). But then there is the…

ok thanks for the information, hoping that feature gets into a next version !

This thread ([URL]) is another good example of why an additional per-user Business license and with portable usage would be highly desirable. The current per-device Business licens…

Whow, it works! Your beta copies all the files one last time, and they all get the correct timestamp! And on the next scan, no new files found. What a pleasure and what an incredib…

The message seems to be clear enough: The user under which credentials you run the FreeFileSync (FFS) sync does not have write access to said location. See e.g. [URL]

I followed your suggestion to uninstall and install the old version and then installed the new donation version and that worked fine. Thank you!

but that's unfortunately not the solution. I see the device nb6163 was activated again. Is there any way to remove the device nb6163.. permanently? Please help. I don't know where …

I'm under Windows 10 with a new install of FFS. My job runs ok in the GUI, the batch job runs if I launch it in explorer, but my scheduled task doesn't run (or maybe more accuratel…

Hello, You have to change a registry key to be able to save a task with no password on your account. See e.g. [URL] for details, or google it.

I ran into the same problem. I think being able to persist checkboxes would be very intuitive. The option to right click and add to inclusion or exclusion filters is a fine substit…

I am having the same error but it is affecting files in a Dropbox folder. Full Disk access is on. I have only seen the error since installing Golden Gate.

The only imaginable situation where a 3 sec-offset and conflict could occur is so complex and bizarre, that the current FreeFileSync behavior is correct and it should *not* be hand…

@Zenju: As a relatively new security measure, the bank now checks whether the recipient name provided for SEPA transfers matches the name on file with the receiving bank for that I…

this support issue can be closed. nothing i did fixed the problem. but the monthly windows update came yesterday. after it ran everything worked fine again. i even checked to make …

Hi, I ran into an unintuitive UI trap regarding how FreeFileSync handles filters when starting with a single folder pair versus adding multiple pairs later. The Problem: When you h…

Reversing the Logic: Reliable Mac-to-Linux File Syncing As is so often the case with cross-platform computing, the most direct route isn't always the one that works. File-syncing b…

I had a response from the Linux Mint forums that explains the issue, sadly, unlikely to ever be resolved. [URL]

What about using real-time synchronization on each of the computers so if you're sitting at computer a and you edit a document the real time sync will recognize that you changed a …

[Quote] That's not true. Empty folders *are* deleted by Versioning. [Quote] You're misunderstanding "maximum". This is maximum version count per file, not "number of syncs".

Thanks, that would be a workaround. I hope though that the current timeout can be reduced to a more reasonable value in a future release (assuming that this is some kind of timeout…

By default FreeFileSync (FFS) gives you a warning (no abort) if there are substantial differences between your left and right location(s). You can disable/enable that warning via t…

Hello, I am trying to understand what happened during a FreeFileSync synchronization on **12 August 2026**, and especially whether some files can still be recovered. The affected s…

I'm using Linux, mint 22,03 and Pop_OS-23,4. [Attachment]

Same issue here at every synchronization. Error message: [Code] I checked the folder and there is no file named "GlobalSettings.xml.363c.tmp" but "GlobalSettings.xml" is here. EDIT…

I ended up restoring my PC from a backup to a time before I tried doing the update and it works now. I'm not sure what was causing it unfortunately and I can't re-create the error …

Hello Bill, I am sorry for your experience. In my case, the flash drive that I was using died. Agent Ransack is not 100% reliable at searching. EaseUS file restore has located and …

Fixed in the next release.

Confirmed, thank you. Adding -DwxNO_IMPLICIT_WXSTRING_ENCODING to the FreeFileSync Makefile C++ flags resolved the wxCStrData ambiguity without patching zen/string_traits.h. FreeFi…

There we go! Alright, thank you Plerry!

I am trying to copy files from my Google Drive folder to my external HD. I've been doing this for years and never had an issue until today. Specifically, a majority of files are co…
