Format USB Flash Drive

Formatting is the method of completely erasing a memory device. Through this formatting process, all data on the drive or disk will be deleted. It also helps to solve most problems in the drive.

Formatting can be done in two ways

  • Using Windows 10 system tool
  • Using a third-party software

  • Here you will get the ‘Disk Management’ window with a list of different disk partitions.

  • Then the USB flash drive will be formatted within a short time.
