How to Convert USB Flash Drive to Local Disk

It is known that a flash drive or USB drive is used as a removable disk in the computer. It is mainly used to transfer data between two computer devices. In this article, you will get to know how to convert a USB flash drive to a local disk in Windows.   

Reasons to convert USB Drive to a Local Disk:

Hence, if your computer is running low on internal storage space, converting USB to a local disk will help you save the storage space. Additionally, converting the external drive to local will also allow you to carry a personal computer on the go. So, you can just plug and play whenever it is required.
