BCWipe ensures that files you have deleted from a disk will not be restored by another person. The program uses military-grade procedures to shred deleted file contents, and it allows you to wipe empty space on your disks. BCWipe is a shell extension for Windows 95/NT and is highly integrated with the operating system. Version 2.13 adds the ability to schedule wipes and to wipe file slacks, the unused space in a disk cluster. This is a 30-day trial. Registration costs $29.95.
