Eraser
What it is
Eraser is a free Windows tool for overwriting sensitive data on drives. It can target files, folders, unused disk space, previously deleted data, and the current user's Recycle Bin. Included erase methods range from pseudorandom data to named overwrite schemes such as HMG IS5 and DoD 5220.22-M. Users can also define a method by setting a pass count and choosing text, hexadecimal, or random data for each pass. A customizable scheduler supports recurring tasks and missed schedules. Optional Windows Explorer integration adds a context menu for supported items; the help documentation also lists a command line interface. The site lists Windows support from XP SP3 through Windows 11 and Server 2012–2025, and says Eraser works with any drive supported by Windows. There are important cautions: the download page says erasure security has not been verified internally or externally, and the code may not remove every trace of files. Unused-space erasure on network drives may also be affected by NAS knowledge and enforced quotas.
