DriveDroid allows you to boot your PC from ISO/IMG files stored on your phone. This is ideal for trying Linux distributions or always having a rescue-system on the go… without the need to burn different CDs or USB pendrives.
DriveDroid also includes a convenient download menu where you can download USB-images of a number of operating systems from your phone (like Mint, Ubuntu, Fedora, OpenSUSE and Arch Linux). Around 35 different systems are available at this moment.
You can also create blank USB-images which allows you to have a blank USB-drive. From your PC you can store files onto the USB-drive, but also use tools on your PC to write images to the drive.
