How to change drive letters in Windows 10

By J. Carlton Collins, CPA

Q. How difficult is it to change drive letters in Windows 10?

A. Changing a drive letter in Windows 10 is relatively easy, as follows. Right-click the Windows 10 Menu button and select Disk Management to display a list of all available hard drives. Right-click the specific hard drive letter you want to change, and select Change Drive Letter and Paths. Click the Add button, select a new drive letter, and then click the Change button, as pictured below.

Notes:

  1. Letters A and B are reserved for floppy drives.
  2. The drive letter for the system volume or boot partition (usually drive C) cannot be modified or changed.
  3. Any letter between C and Z can be assigned to a hard disk drive, CD drive, DVD drive, portable external hard disk drive, or USB flash memory key drive.
  4. If you change the drive letter for drives where applications or programs are installed, those applications or programs may or may not function properly after the change because they might refer to the original path used to install those products. In this case, you would likely need to reinstall those applications or programs for them to work properly.
