Knoppix (bootable CD, x386): This works similarly to a USB drive in that the bootable CD boots the user's files from their PC hard drive to another disk using a Linux desktop.

Restoration (Windows): This is a portable recovery tool that doesn't have any real bells and whistles. This free software works with all available versions of Windows. While advanced functionality is not available for this software, users can still perform basic searches.

Undelete Plus (Windows): This software, which was previously commercial, now offers a lengthy freeware run touted under a "limited time offer" claim. This software works for every available Windows platform, as well as FAT and NTFS.
