For different reasons, FreeFileSync (FFS) writes files at the start of its sync or during its sync, that are removed when/after the syncs ends.
This can be a sync.ffs_lock file (see LockDirectoriesDuringSync)
Or it can be one or more temp-files.
Unless you have disabled "Fail-safe file copy" in the FFS GUI Tools / Options, if a file is copied to the opposite side, the existing opposite-side file (if any) is temporarily retained, and only if copying the new file was successful, that retained previous file is deleted, moved to the recycle bin or moved to the versioning location, depending on your "Delete files" method you selected.
FFS uses its (in)famous *.tmp file extension to temporarily effectively have two files (the old one and the new one) of the same name in one and the same (sub)folder.
