I have a question about file copying between laptop and table computer. Both have Dopus 10 in Windows 7. The laptop mounts P: to table computer. Table computer is shutdown and laptop is sleeping. Next morning I start both computers. I then copy a file from the laptop to P: which is still mounted. However, I cannot find the file on the table computer.

Very strange, I tried again now half a day later and this time it worked ! / ?

I don't know what happened, I cannot repeat it.

Have a look in the File Log (Help menu -> Logs -> File Log). If logging is turned on then it should have a record of the file being copied and tell you where it was copied to.
