It’s all in one tool. Features come with cluttered interface. If you don’t know what are you doing, don’t use it. I personally do not recommend it if you want a simple bootable USB to install new operating system.The special feature of RMPrepUSB is you can create a partition in USB drive just like you do on your hard disk making it more useful for saving files plus using the same drive as a separate folder for storing files.
This keeps your files separate from the operating system files.
For advanced users.
Difficult to use
