East-Tec Eraser is a secure data destruction utility that wipes files clean beyond recovery.
Eraser does a very good job at destroying data beyond recovery. Its extensive erasing capabilities make sure that not even a trace remains after erasing a file or folder. Eraser has several wiping (or overwriting) methods, differing in speed and security. The fastest ones offer normal security while the slower ones match the specifications of the U.S. Department of Defence and can even stop hardware recovery tools.
Eraser can be run through command-line options or interactively and it allows you to define your own wipe methods.
This newest release has an "Erase for Good" feature that can destroy any data from previously deleted files that may still be accessible on your disk. A new "Sensitive Data Cleaner" clears the contents of folders that usually contain sensitive data, including your Web browser cache (or Temporary Internet files folder), cookies, history, the recent document list, and more. In addition, Eraser now integrates more smoothly with Windows.
