A high performance free space eraser.

Get it on F-Droid What is free space erasing?

Typically when you delete a file it is not really deleted, it is merely removed from the file system's index. A free space eraser tool such as this one fills the remaining space of your drive with random noise files and then deletes them. This process makes deleted files for the most part irrecoverable.

What is file table filling?

On some file systems, deleted file names can still be accessible in backup index databases. By creating many tens or hundreds of thousands of empty files with different random names you can push out the old files. This process makes deleted file names for the most part irrecoverable.
