Many of the folders and files will not have their original name, or even their original "extension"
You basically go through all the files and folders, using hints such as their size and folder to identify them. Try re-naming them with the correct extension and opening them. Using different programs to attempt to open them might help to identify their original names.
Sounds Fun, thanks for the help! I guess it's better to have to do this then loose the files permenantly?
