(Secure Delete) is a command-line utility developed by Mark Russinovich (Microsoft Sysinternals) that securely deletes data by overwriting it. This guide provides practical examples of how to use SDelete to ensure your sensitive data is permanently erased.

If you want to wipe an entire folder, including all subdirectories and files within it, you use the -s (recursive) and -r (remove read-only) flags. sdelete64.exe -s -r C:\SensitiveData Use code with caution.

The most basic use of SDelete is wiping a specific file so it cannot be recovered by forensic software. sdelete64.exe C:\Users\Admin\Desktop\passwords.txt Use code with caution.
