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: Nearly all 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 may be a little more secure but still not delete all data, though it will put additional wear on your drive.
Version Note: There is a newer version of Eraser, Eraser 6.x, which is a complete rewrite of the tool. It relies on the .NET framework 4.0+. We'll be releasing a version of this tool in the future as a separate app as it will not work on as many PCs as standard Eraser 5.x.
Updater Icon/Interface: The icon, toolbar, and interface of Eraser has been modernized for Eraser Portable by the PortableApps.com team.
