Shreds and permanently deletes files so you can be completely sure the data is gone. It works thanks to DD cmd. This overwrites data and then removes the file entry from the filesystem.

You can select a single file instead of a directory. Obviously, the recursive option won't have any effect.

On Android 4.4 and later, fstrim auto-runs periodically and resets unused memory cells, so this flow is only useful if you want to shred files immediately.

Because this doesn't use root, there's the possibility that some memory areas remain untouched. Except if you are overwriting an HDD in which case ~99% of the data is being "touched", but you should overwrite multiple times because HDDs have strong magnetic storage
