What Is a Drive Letter
Windows assigns a drive letter (A-Z) to any physical computer disk or drive partition, making it accessible.
The system reserves drive letters A: and B: for floppy drives and portable media, but you can assign them manually. The default drive letter is C: for hard drives, and the CD-ROM drive is assigned the next available letter, typically D:. The drive letter C: can only be assigned to the drive where Windows or MS-DOS is installed.
In Windows, the C: drive is always assigned to the primary hard drive, and is not affected by the presence of other operating systems or secondary storage devices, such as DVD drives or external hard drives. This means that even if you have multiple operating systems installed, the C: drive will always refer to the primary hard drive, regardless of the number of other drives or devices present. Floppy disks, which were once common, are no longer typically used in modern computers. As a result, the C: drive is usually assigned to the primary hard drive, and the D: drive is often assigned to a secondary storage device, such as a DVD drive or external hard drive.
Windows assigns the last drive letter to external drives, and you can change it to any available drive letter. For example, if the last drive letter was F:, a new drive would be allocated as G:. If you add more drives or partitions, they would be allocated to letters like D:, E:, F:, G:, and so on. You can change the assigned letter to any available letter.
How Assigned Drive Letters Work
Windows assigns a drive letter to an external drive, but you can change it. The new drive letter is saved in the registry for each drive and volume ID, not permanently assigned to the device itself. If you unplug or change the drive, the letter may revert.
When you insert multiple USB drives, you may notice that the drive letter changes each time. This is because Windows assigns letters from D and onwards in turn to non-assigned drives. If a previously assigned drive is not plugged in, its letter will be reassigned to another drive. If you plug in a drive that was previously assigned a letter, it will be given the next available letter instead.
Windows provides several options for changing the drive letter of your computer, and this guide will walk you through how to assign drive letters using three different tools: Disk Management, Qiling Partition Master, and the Windows Command Prompt.

Step 2. In the Disk Management window, right-click the volume you want to modify and select "Change Drive Letter and Paths".
Step 3. To assign a drive letter to a drive, select the drive from the list, then choose to add or change the drive letter.
