Formatting your cards with the Format SD Card app is a great way to ensure your data is deleted and unrecoverable, allowing you to sell or exchange your device with a peace of mind. This app is capable of installing NTFS, FAT, and EXT file systems on any MicroSD or SD card plugging into your Android device.

The Format SD Card app is lightweight, taking up only 1.42mb on your phone or tablet, and can be left installed for convenient future use.

This app can also be used to repair memory cards that contain errors and aren't accessible by the Android operating system.

You don't need to understanding the inner workings of a file system to use this super-simple mobile app. Simply install the app and click "Erase SD Card" to get started. Without the frill and bloat of many formatting apps, this application manages to get the job done lightening fast, without taking up much room on your phone.
