I take it by 'deleted' you mean "deleted permanently from the Recycle Bin". The answer is 'Yes', and you need the right software.
Disk Doctors is one I found by searching on Google, but there are quite a few decent ones out there I believe, and free too (even if it's just the trial version).
Two things you must not do though before you've run the file recovery software (to increase the chances of you getting your stuff back):
1. Don't create new documents.
2. Don't run the Disk Defragmenter tool.
Goodluck! And after this if you can, run regular backups.
