The Devourer
The Devourer is a free, open-source portable Windows utility for best-effort shredding of individual files.
What The Devourer is
The Devourer is a free, open-source portable Windows utility for best-effort shredding of individual files. It overwrites a file’s primary stream and detected NTFS alternate data streams in four passes: zeroes, ones, cryptographically secure random data, then zeroes. Normal, Aggressive, and Extreme modes are available. Aggressive adds a Windows ReTrim request, while Extreme also fills same-volume free space with temporary random data. Before overwriting, the utility checks media type, TRIM, BitLocker, and Volume Shadow Copies and displays warnings when needed. It rejects directories, symbolic links, reparse points, files with multiple hard links, and files locked by another process. Files are processed locally, without telemetry, analytics, accounts, remote storage, automatic uploads, or runtime network API. The portable x64 release runs on Windows 10 or 11 and handles one regular file at a time without an installer. Administrator access is required only for Aggressive and Extreme modes. The project uses the MIT License. Its guide says the release executable is unsigned and recommends downloading from the official repository and checking its SHA-256 checksum. It cannot guarantee physical erasure across SSD wear leveling, snapshots, backups, cloud-sync replicas, or other copies.
Good
- Uses four overwrite passes
- Checks storage conditions and displays warnings
- Processes files locally without runtime network API
- Portable app requires no installer
- Free and released under the MIT License
Watch out
- Handles one regular file at a time
- Does not support folders or drive wiping
- Cannot guarantee physical erasure across all copies
- Release executable is not code-signed
Who it suits
The Devourer suits Windows users who need to overwrite one regular file at a time. Its guide describes Normal mode as appropriate for most users and Extreme as a special-case option that can take a long time and write heavily to a drive.
Verdict
The Devourer offers local, multi-pass shredding with safeguards and storage warnings, but it cannot assure physical erasure across every storage behavior or copy. The unsigned release and checksum guidance are worth noting before use.
