Error Code 1920: The file cannot be accessed by the system. (MoveFileEx)

I got several synchronization errors while execute the file sync task.
Some other files in this directory can be copy to the destination, but only 2 are failed.

Here's the error log of the case:

|10/21/2013 - NYC: Synchronization completed with errors

May I know what's the cause of issues?

Can Anyone give me some advice for the above problem?
Thanks a lot.

I am having the same problem. I can manually copy the files from source to destination but freefilesync seems to have trouble doing that!

The network device seems to have a problem with FFS's sequence of first creating a .ffs_tmp file followed immediately by a rename operation. You can probably solve this error by disabling "fail-safe file copy" in global settings, but then... well, the file copy is not fail-safe anymore and will corrupt a file in case of a crash. This behavior is not worse than what Windows Explorer does, but still not good enough.
