A lot of free data recovery software are available in the market. If you wonder how they are able to recover your data easily, the answer is that the data wasn’t deleted from your system at all. When you empty your system’s recycle bin or use SHIFT+DEL to delete a file or folder, the operating system merely marks that space as unoccupied. Later, when new data is written at the same location, the original data gets completely deleted.
Free Secure Delete software for Windows 10
This could be a problem for those who intend to permanently delete confidential data. The deletion tools which delete data in a manner that cannot be recovered are called secure delete software products. Let’s take a look at some free secure eraser or shredder software for Windows 10/8/7:
- Prevent Restore
- File Eraser
- File Shredder
- Smart Disk Cleanup
We have already taken a look at Free File Wiper, SDelete, Cipher, Microsoft Surface Data Eraser, CCleaner, DBAN, OW Shredder, and DeleteOnClick. Now let us take a look at some more Secure Delete software.
The SecureDelete software securely overwrites deleted files using the Gutmann and DOD 5220.22M algorithms so that the files can never be recovered. It also uses another faster, though less secure algorithm to securely delete your files. The procedure is simple. Use the options to add files or folders on the app and then click on the option to delete them. Select Empty Recycle Bin on the app to securely delete the files and folders.
SecureDelete also has options to clear the paging file at shutdown. Paging files work as a supplement of the RAM and some expert hackers can use it to recover securely deleted data. Thus, SecureDelete is excellent free software for protecting your data. Check more about it on the company website here.

Freerazer uses the “shredding” technique to securely delete data. It shreds the space occupied by your deleted data. This way, the data becomes unrecoverable. The software modifies the data into something unreadable before deleting it and then shreds the space occupied by the data after ordinary deletion. This way, simple data recovery tools cannot retrieve the deleted data. However, this procedure isn’t fool-proof. Experts might be able to retrieve a part of your deleted data by checking through the paging file, though that rarely happens. The tool can be downloaded from freeraser.com.
