When I try to back up many files from my work environment directly to my Microsoft OneDrive using FFS, I get an access denied error.
I never noticed this error before because I only ever sync a few files at a time, and everything worked fine. Now, however, I wanted to back up a larger number of files and keep getting the same error.
I suspect that FFS creates a file, and OneDrive then tries to claim this temporary file, and FFS no longer has the necessary permissions to access it. Because if I temporarily disable OneDrive syncing, I can sync all the files without any problems.

Can you post the error exactly? Access errors can be caused by tons of reasons

Unfortunately, the description doesn't provide much more information.
"C:\User\file.ffs_tmp" cannot be renamed to "file.png".

If I can enable any kind of debug mode, I'll gladly do so to find the error.
