If you are using Windows, the data will first go to the recycle bin. If you have not emptied the recycle bin, you still have access, and can simply move the data back where you need it.
If the data has been deleted from the Windows file system, the data is still there. It just is no longer associated with the directory. There are varieties of tools that can be used to recover the accidentally deleted file. One such tool is OnTrack's EasyRecovery software , but there are many others.
The best technique is prevention. Several programs replace or supplement the recycle bin, but the best known is Undelete. This program creates a recovery bin that allows you to recover deleted data that would be irretrievable with the standard recycle bin. For more information, go to http://www.undelete.com .
Hope this helps.
