Eraser Portable 5.82 Rev 3
Eraser Portable is a secure file-deletion and data wiping utility. With support for multiple wipes, pattern writing and more, it can be used to securely delete any sensitive data.
Flash Drive Note: Most modern flash drives use wear leveling to spread write operations out over a device. This interferes with Eraser (and other secure deletion utilities) ability to wipe single files. Wiping an entire drive or erasing a file and then wiping free space should still work securely, though it will put additional wear on your drive.
