How to Copy USB to USB in the Fastest Way? Freeware Download

When do you need to copy USB to USB?

USB flash drive is a quite convenient tool because they are portable. As a handy little storage device, a USB drive makes transferring data between different computers very easy. People can use it to back up their important data or transfer data from one computer to another.

However, copying your USB drive to another one is necessary for some situations. For example, when your current USB drive gets filled up and you need more space, you can clone it to another larger USB drive for an easy upgrade. Besides, when the old USB flash drive is about to fail, you can copy it to another one for data security before it totally stops working properly. 

Fastest way to clone USB (flash drive) to USB(flash drive)

But, how to copy USB to USB drive? To copy USB drive to USB drive seems like duplicating a USB drive. The basic way is to copy files in Windows Explorer. Plug the two USB drives into your computer and make sure they can be detected. Open the Windows Explorer, select the files on the old USB drive, right-click it and select Copy. Then, Paste them to another USB drive.
