Normal File Deletion is NOT secure. Deleting files merely removes the file system's pointer to the file, ALL THE DATA REMAINS ON YOUR HARD DRIVE. The remaining data can be easily recovered with data recovery or forensic software. Your sensitive files may also be vulnerable to advanced recovery techniques, EVEN WHEN OVERWRITTEN, by analyzing latent magnetic traces.
Mutilate File Wiper is a file shredder or file eraser that securely deletes sensitive files. Use Mutilate to prevent attempts to recover sensitive deleted files from your hard drive by data recovery or forensic software. The program overwrites all bits in selected files, including cluster slack space, with binary 1's, 0's, and/or random bit patterns. Choose from three security levels and a customizable level with up to 297 overwrite passes. Mutilate supports complete folder deletions including subfolders. With Mutilate's disk free space wiper, you can even use Mutilate as a file remover to destroy previously deleted files on your hard drive. And, you can store up to thirteen folders in Power Mutilator for quick access to files or folders you target routinely.
