How To Mount a Folder as a Drive in Windows 11 & 10

Learn how to make any folder appear as its own drive in Windows 11 and 10. This guide shows you how to map or mount a folder to a drive letter.

Most people don’t know this, but you can map any folder on your computer to make it appear as a drive in File Explorer. Once you’ve done that, you can also configure Windows to automatically mount the folder as a drive on startup. This allows you to treat a folder just like any other drive, like the C drive, D drive, etc. For example, you could mount a deeply nested network folder to a drive letter for quick access, mount cloud folders like Dropbox or OneDrive as dedicated drives, or map a favorite local folder to make it instantly available in File Explorer.

So, without further ado, let me show you the steps to mount a folder as a drive in Windows 11 and Windows 10. Let’s get started.

Before You Start

• Even after mapping a folder to a drive letter, you can still access the original folder directly through its original path or by navigating to it in File Explorer.

Mount a folder as a drive in Windows 11 & 10

We’ll use a special command called subst to map a folder to a drive letter and mount it as a drive in File Explorer. Here’s how to do it.

1. Press the “Windows key + R” shortcut.
2. Type “startup” and click “OK“.
3. Right-click in the folder.
4. Select “New” > “Shortcut“.
5. Type subst X: "C:\path\to\folder". X is the drive letter you want to assign.
6. Click “Next“.
7. Type a name of your choice in the blank field and click “Finish“.
8. Double-click the shortcut we just created.
9. The folder will mount as a drive in File Explorer.
10. Every time you restart, the folder will automatically mount as a drive.

Detailed Steps (With Screenshots)

First, decide whether you want the folder to automatically mount as a drive at system startup. If you want that, press “Windows key + R” to open the Run dialog box. Next, type “startup” and click “OK” to open the startup folder. Otherwise, go to the desktop by pressing the “Windows key + D” shortcut.

Next, right-click on an empty space in the folder (or on your desktop), select “New“, and then choose “Shortcut.”

The above action opens the shortcut creation wizard. In it, type the following command while replacing X with the drive letter you want to assign and "C:\path\to\folder" with the actual path of the folder that you want to appear as a drive. Click “Next” to continue.

subst X: "C:\path\to\folder"

Now, type a name of your choice in the blank “Name” field and click “Finish“.

That is it. You’ve created a shortcut that maps a folder to a drive letter.

Simply double-click the shortcut, and the folder will be mounted as a drive with the drive letter you chose in the command. If you’ve created the shortcut in the startup folder, Windows will automatically mount the folder as a drive at system startup.
