A USB flash drive or pen drive can be used for a lot of things. It allows you to keep important files outside of operating system, run portable version of programs and games, create Windows recovery disk, create Windows installation media, try open-source operating system, etc.

As it is cheap and convenient, many users have one or more USB drives for a certain purpose, and in some cases, a USB clone tool is in need to create an intact copy of the USB for backup or migration:

▪ Copy your USB drive as a backup: Since USB drives are small and light, they are easily lost. And with numerous times of plug-in and plug-out, your USB drive can get poor connection, or infected by virus from a computer. To avoid unwantted data loss, you can keep a USB duplication as backup.

▪ Clone a bootable USB drive for migration: Cloning is different from just copying and pasting the files from one to another. Simply copying may skip some crucial files, causing portable programs corrupted or OS unbootable. A USB drive clone can migrate everything to another drive without affecting the original functionality.
