I suspect there is something else going on. FreeFileSync supports Unicode fully, including emojis.

Unfortunetely looks like there's still no solution..

I just switched to a fresh Win10 installation (build 19044.2006) with FFS V11.25 and now I'm getting the same error:
ERROR_FILE_EXISTS: Die Datei ist vorhanden. [CopyFileEx]

Process monitor also shows the mentioned lines:

Get-SmbConnection shows I'm using SMB V2.1 for connection to my QNAP NAS

I will be happy to assist with testing betas etc..

That's definitively the SMB bug that FFS could try to workaround. I'll prepare new beta versions for testing.

both betas are working, showing no error, copying the intended file and leaving no .ffs_tmp file behind.

Also when I reinstalled 11.25 Release version the error came back (as expected).

I sent you the PML files...

Thank you very much! The workaround is doing as expected according to the PML files. The fix will be officially available in the next version FreeFileSync 11.26.

Cool, thank you!
In the meantime I'll use the beta...

Hi,

I am not a FFS user, however I stumbled upon this thread while trying to understand why I was getting empty files being created and weird "The destination already has a file named X" errors from Explorer while attempting to copy files to a Samba share.

This is indeed a Samba bug, and I took the liberty of filing it against them: https://bugzilla.samba.org/show_bug.cgi?id=15563

The bug happens when Samba is configured with `ea support` enabled (note this is the case by default starting from Samba 4.9) and one attempts to create a file with extended attributes and the underlying filesystem does not support user xattrs.

Probably the cleanest solution is to ensure Samba is serving from a filesystem with user xattrs support.

Otherwise, a workaround is to explicitly set `ea support` to `no` in Samba smb.conf. This will disable extended attributes, but those are rarely useful, and this makes no difference if the underlying filesystem doesn't support them anyway.

Interesting discovery @edechamps. Thanks for your work on this and for dropping a note in here. I may see if I can fiddle with my smb conf settings on my NAS - though I haven't encountered the errors in FFS for a while now.
