Change Drive Letter Using CMD in Windows 11

Managing drive letters in Windows 11 can be performed quickly using the built-in DiskPart command-line tool within the Command Prompt. This guide provides step-by-step instructions on how to open an elevated Command Prompt, identify your target partition, and assign, modify, or remove its associated drive letter.

Step 1: Open Command Prompt as Administrator

  1. Press the Windows Key + S to open the Windows Search bar.
  2. Type cmd.
  3. Right-click on Command Prompt and select Run as administrator.
  4. Click Yes if prompted by User Account Control (UAC).

Step 2: Launch the DiskPart Utility

In the Command Prompt window, type the following command and press Enter:

diskpart

Step 3: List and Identify the Volumes

To view all available partitions and their current drive letters, run:

list volume

Note the Volume ### number and the current letter assigned to the partition you want to modify.

Step 4: Select the Target Volume

Select the volume you wish to modify by replacing X with the specific volume number from the list:

select volume X

(Example: select volume 3)

Step 5: Assign or Change the Drive Letter

To assign a new drive letter or change an existing one, run the following command, replacing Y with your preferred drive letter:

assign letter=Y

(Example: assign letter=E)

Note: Ensure the letter you choose is not already in use by another drive or partition.

Optional: Remove a Drive Letter

If you want to unassign or hide a partition’s drive letter without deleting the data, use the remove command:

remove letter=Y

(Example: remove letter=E)

Step 6: Exit DiskPart

Once you receive the confirmation message that the operation succeeded, close the utility and Command Prompt:

exit

Type exit once more or close the window. The new drive letter will now be active and visible in File Explorer.
