What happens when a user deletes a file on their Windows XP computer? The file is moved to their Recycle Bin. That way, if the user later changes her mind and wishes she hadn't deleted the file, she can open her Recycle Bin, find the file, and right-click on it and select Restore and the file will be restored to its original location on her system.
What happens though when a user accesses a shared folder on the network and deletes a file in it (assuming she has permissions to do this)? Does the file move to the Recycle Bin on her computer? No. Does it move to the Recycle Bin on the file server? No. It just gets deleted, just like when the user selects a file on her own system and presses SHIFT+DEL.
How can you avoid this kind of thing from happening? Use shadow copies on the file server, which requires Windows Server 2003 or later. See Introduction to Shadow Copies of Shared Folders for more details.
