USB Tools is an all-in-one utility application designed for Android devices, aimed at managing and maintaining USB drives without the need for a PC. It offers a wide range of features including formatting, partitioning, and testing USB drives, along with the ability to back up data. Users can format drives to various file systems, manage partitions, and even perform diagnostics to detect fake drives or bad blocks. The application supports both OTG devices and internal SD card slots, although the latter requires root access for full functionality.

The app also includes specialized tools for gaming, specifically for managing PS2 and PS3 games. Users can import, organize, and convert game files, enhancing the gaming experience directly from their mobile devices. While many features are accessible for free, advanced actions require tokens that can be earned through ads or purchased. USB Tools is ad-supported but offers a Pro version to remove ads and unlock additional features.
