mirror files

[nordelch]

Hello,

I already own the program FreeFileSync for some time.
Due to a new set up of my WLAN, I had to reconfigure the program now synonymous.

I used to be able to mirror my files from disk to my NAS server.
The first time, all files were mirrored and later "only" changes.

When I change a file, it mirrors all the files, even though I did not change them.
Does anyone have a hint? Or knows what I can do?

Thank you and greetings
