Hello and Thank you!

after deleting apple temporary files I still dont have any improvement with copying reliably.

But I am quite certain now that the problem has to do with the .DS_Store files OSX creates. I just tested this by copying a folder where i deleted .DS_Store via terminal: copying worked. Of course that can not be the solution, becaues OSX creates a new .DS_Store everytime i open the folder.

I am not sure if this can help: http://support.apple.com/kb/HT1629, but reading carefully i dont think so ("These steps do not prevent the Finder from creating .DS_Store files on the local volume, and these steps do not prevent previously existing .DS_Store files from being copied to the remote file server.").

My question is: Can this have to do with the DSS-Option "Hide special folders" in NAS-Config? I would try if this is it, but the your manual says that this option should not be altered when there are files on the server. Or is it save? (Or does not have anything to do with it?)

Thank you again in advance,

Florian
