How to Securely Delete Files on Android

With the programs we'll list for you, you can permanently delete any type of file from your phone. These shredders remove any trace of the file, making any attempt at recovery almost impossible. The environments use several data shredding methods multiple times, overwriting the storage space with different combinations of 0s, 1s, and random characters.

The tools also include a verifier that checks the destruction of deleted files in real time. This way you'll be sure that no traces of the data remain on your device.

Andro Shredder

Andro Shredder is one of the best free options for permanently deleting files on Android. The utility features nine different destruction methods, classified by their shredding power. From its interface you can select the file or folder to delete, or schedule tasks to delete directories or the clipboard daily, weekly, or monthly. If you select a specific folder on your device, you can choose the type and age of the files to delete.

SHREDDER: Data Eraser

SHREDDER: Data Eraser supports more than 10 advanced data destruction methods. You can permanently delete any file from internal storage or stored on the SD card using platform standards once or multiple times, making recovery impossible. The environment lists your phone's files, sorting them by category (media, WhatsApp folder, etc.), and then you can select one or more data items and permanently delete them.

Some of its shredding standards are:

• US DoD 5220.22-M (shreds files 3 times)
• British HMG IS5 Baseline (shreds files once)
• NSA 1302-2 (shreds files 2 times)

Shreddit – Data Eraser

Shreddit – Data Eraser is another very good file destruction platform. The utility's gallery-style interface makes it easy to identify files, though you can also use the explorer. It also has a dedicated section for destroying WhatsApp files. Unlike the other tools, this environment doesn't offer the option to select the destruction method.

SDelete – File Shredder

SDelete – File Shredder is an environment compatible with multiple international data destruction standards. By default it uses the British HMG IS5 standard, but you can manually select any method you like. The utility also supports batch file deletion.

True Shredder

True Shredder is a very good data destruction platform for Android. The program lists files in the following sections: Images, videos, audio, and files. You can select multiple data items to permanently delete them from your mobile device. It's not the best option, but it is one of the simplest to use.

With the five platforms to delete data permanently from your mobile device, you'll erase all traces of the file so that no one can recover them.
