SPECIAL TOPICS - ELECTRONIC FILES/DOCUMENTS   Individual Electronic Files/Documents   To securely destroy electronic files that are appropriate for destruction, contact your local support provider (LSP) for options.    For example, individual files can be securely destroyed using the PGP Shred function on Windows machines.    MacOS 10.3 and later supports secure file deletions without need for third party products. To delete files so that they cannot be recovered, choose Finder > Secure Empty Trash. Files deleted in this way are completely overwritten by meaningless data. This may take some time, depending on the size of the file. To prevent the recovery of files you deleted previously, open Disk Utility (in Applications/Utilities), choose Help > Disk Utility Help, and search for help on erasing free disk space.
