External Drives Listed Twice (Duplicate) in File Explorer Navigation Pane

Disk drives (both fixed as well as removable drives) appear under the “This PC” category in File Explorer navigation pane. In addition, each removable drive will be pinned as a separate category, appearing after “This PC” and “Libraries” section — that is, the drives appear twice in the navigation pane. This double-listing can sometimes cause confusion to the users. To remove the duplicate or redundant disk drives from navigation pane, here is a quick registry fix.

  6. Exit the Registry Editor.
  7. Logoff and login back for the change to take effect.

    To apply the setting for all users in the computer, make the modification under HKEY_LOCAL_MACHINE — in the registry path below:

That’s it! The duplicate drive letters for your external drive should no longer appear on File Explorer.

Registry File

To automate the above setting, download remove-duplicate-drives.zip, unzip and run the enclosed REG file. Logoff and login back after running the registry file.

More Information

{F5FB2C77-0E2F-4A16-A381-3E560C68BC83} is the control that enumerates removable drives and shows it in the navigation pane, next to Libraries. This is in addition to the listing shown by This PC. By preventing this control by using the NonEnum registry key, the enumeration of removable drives and their duplicate appearance is prevented.

  1. I tried your suggestion but it didn’t work. I also tried another suggestion from another site without success. I admit to being confused. When you say Create a new DWORD, how do you do that? Same thing for “Set the data…” Given that I did my best to follow you but nothing works. Is there something I did wrong? Help!!!

    • @Gilbert: Go to the mentioned branch. From the Edit menu, click New > DWORD (32-bit) value. Follow the rest of the instructions.
