A copy remains in the chest, confirm that the file has been copied back to the original location and if so delete the copy in the chest.
That is by far the safest way (regardless of what the help file happens to say) as if there was a problem whilst restoring you could lose the only file copy.
I almost missed your post as you have posted it in the wrong forum, this one is using the avast 4 server version, which I presume you aren't using. It would have been better in the topic where you previously posted.
