Hi all,
first of all I really like FreeFileSync, it became my preferred software to backup my mac os stuff.
I'm currently using v. 10.22 on mac os Catalina 10.15.4 (19E287): the OS runs inside a virtual machine based on a linux system.
Within this virtual machine I can share an NTFS drive (and it is an smb volume), so my primarly use of FreeFileSync in to syncronize files in mac os with this NTFS drive.
My workstation is able to boot also a windows 10 operating system, with this NTFS external drive (D:\).
I noticed that the files syncronyzed from mac os are directly accessible from windows 10, but I can't copy/move them from this external drive D:\ to the main drive C:\
After some days, I was able to track the issue thanks to the microsoft support forum.
The issue was due to extended attributes in files.
So, back to mac os, I deleted all the extended attributes in the files on that NTFS drive with command:
xattr -rc /Volumes/6TB

N.B.: /Volumes/6TB is the path to the NTFS drive

and now I'm able to copy again files in windows from D:\ to C:\; so my question is: can I set somewhere in FreeFileSync an option to NOT copy extended attributes when syncronyzing files?

Thanks!

Daniele

Some more info about the file (with extended attributes) I wasn't able to copy back from D:\ (NTFS) to C:\ (NTFS) in windows 10, after the syncronization mac os --> NTFS share (D:\):

Just to add some more info to the issue and solution, as the root cause should be samba server settings..

The cause of the issue were settings in the samba server: in my operating system (Unraid), into which my mac os vm runs, I have an option called "Enhanced macOS interoperability" which I turned on, thinking to optimize transfers from my mac os vm to the ntfs/smb drive.

By turning it off, attributes of files are stripped off when files are copied, so there is no problem anymore in copying them in windows from D:\ to C:\.

I have no full information about what that setting enables in details, but it has something to do with vfs objects = fruit (Enhanced OS X and Netatalk interoperability).

I will update this discussion if I will have more info about specific settings in the smb server.
