Echo Sync always wants to overwrite existing files

[Volka-Ot]

I bought the Windows Version of FilesyncToy and since then the Echo Sync function is not working as expected:

• I created the folder pair for the "echo task" and copied the files from left to right with the tool
• afterwards: when pressing the "preview button" the tool wants to "overwrite" all existing files on the right folder, although not change of the data

Like this I cannot use the tool anymore, because it takes hours to sync everything although there is no difference in the data.
Where might be the problem?
Thx

I have the same problem. I want to "echo"folders from my pc to a NAS at my router. With my old pc everything was fine ("old" filesync by microsoft). With my new pc I bought the latest version. The first run works fine. The second run later overwrites every file no matter whether it has changed or not. The same with an external ssd that is connected to a usb-port. What is different to my "old" pc setup, that I want to echo files that are synchronized with onedrive. I work with windows 11.

Has anybody an idea?
Thank you.
