Before reviewing the below recommendations and suggestions, verify that the files have actually been deleted; in some cases the files may have simply been moved. You can search the hard disk drive for the files you believe to be missing by running find or search on the computer.
Recover file from backup
If the file has been backed up to floppy disk or other medium it is recommended that the file be restored from that backup if the file cannot be found.
