Space Scrambler

Category: Utility - Windows 64bit

Space Scrambler 4.2 is a utility designed to overwrite free disk space with random data, making previously deleted files significantly harder to recover. The program works by creating temporary files (named TODELETE.TMP, TODELETE2.TMP, etc.) that fill available free space. These files can be safely deleted after the process completes. The software supports multiple overwrite passes and adjustable chunk sizes to improve coverage. This free utility is ideal for securely scrambling all data on USB sticks, SSDs, or hard drives before selling, giving away, or losing them.

There is much more to come

Although two of the three computers I use daily run Linux, the first free programmes I put on the software page are for 64‑bit Windows (Windows 7 and later). Linux versions are coming soon!

There will be many more programs and utilities added to these pages. I am currently engaged in teaching and completing ongoing projects—please check back soon.
