Slow networkdrive makes FFS think files were deleted?

[KayMS]

Hallo all,

with FFS 9.2 I want to synchroniz files/folders between on network drive (is the "master") and a laptop.
Files on both sites are equal (name, timestamp), but after comparison FFS says that the files of some folders on laptop aren't on network drive (but they are on network drive!). So he deletes them on laptop. At next comparision, FFS recognizes, that this files are on network drive, but not on laptop, and copys them to laptop.

Another thing: Compare the equal sources (network drive and laptop), FFS says, there are some files on laptop but not on network drive - and wants delete on laptop. I DO NOT sychronize but repeat the comparison. Result should be the same, but now other files are marked as not on network drive but on laptop. But they are on network drive and he shell not delete them on laptop.

The performance to network drive sometimes is very low. Maybe, if network drive is unavailable for a second while comparison FFS thinks there are no files on network drive?

Thanks very much for a hint,
Kay
