Change, add, or remove a drive letter


You must be logged on as an administrator to perform these steps.

Windows typically assigns a letter of the alphabet to most drives. If you want to organize your drives in a certain way, you can change the drive letter.

You can assign any letter to a drive as long as long as the letter isn't already in use by a different drive.

To see which drive letters are in use

  • Open Computer by clicking the Start button Picture of the Start button, and then clicking Computer.
