Overview

Eraser is a free Windows security tool for overwriting sensitive data on drives. It can erase files and folders, previously deleted data, unused disk space and the current user’s Recycle Bin. Its methods include pseudorandom data and named overwrite schemes such as HMG IS5 and DoD 5220.22-M. Users can also define custom methods by choosing a number of passes and specifying text, hexadecimal or random data for those passes. A customizable scheduler handles recurring tasks and missed schedules. Optional Windows Explorer integration adds a context menu for supported items, and the help documentation lists a command line interface. The site lists support from Windows XP SP3 through Windows 11 and Server 2012–2025, and says Eraser works with drives supported by Windows. The download page cautions that erasure security has not been verified internally or externally and that the code may not remove all traces of files. Unused-space erasure on network drives may also require NAS knowledge and may not handle enforced quotas as expected, even when a task reports success. Eraser costs 0.00 USD per free.

Who it is for

Eraser suits Windows users who want to overwrite files, folders or unused disk space, including through scheduled tasks. Its custom methods may also suit users who want to set their own pass count and pass data.

What is good

  • Erases files, folders and unused disk space
  • Includes named and custom overwrite methods
  • Scheduler handles recurring tasks and missed schedules
  • Optional Windows Explorer context menu
  • Works with drives supported by Windows

What to know first

  • Erasure security has not been verified
  • Code may not remove every trace of files
  • Network-drive unused-space erasure can mishandle quotas
  • No macOS or Linux support

Verdict

Eraser offers several erasure targets, configurable methods and scheduling on Windows. Its stated security caveat and network-drive limitations are important to consider before relying on it.
