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.

Remove duplicate drive-letters in File Explorer

  1. Right-click Start, click Run.
  2. Type regedit.exe and click OK to open the Registry Editor.
  3. Go to the following branch in the Registry Editor:
    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies
  4. Create a subkey named NonEnum and select it.
  5. In the NonEnum key, create a new DWORD value named {F5FB2C77-0E2F-4A16-A381-3E560C68BC83}
  6. Set the data for {F5FB2C77-0E2F-4A16-A381-3E560C68BC83} to 1

  7. Exit the Registry Editor.
  8. Logoff and login back in for the change to take effect.
    Note: To apply the setting for all users on the computer, make the modification under HKEY_LOCAL_MACHINE — in the registry path below:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\NonEnum

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 in 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.

The above registry edit has been tested to work in all versions of Windows 10, including v2004.

  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.

  2. If running 64 bit, would you type that instead of 32 ? Ps in my case it is a WD Passport drive (G) and it duplicated on my (F) drive which is my CD drive. Both drives say
    WD unlocker
    Extra
    Locale
    Autorun.inf
    WD drive unlocked.exe
    I am running Windows 10 home 64 bit, ver: 1909
    Thank you

  3. I have added {F5FB2C77-0E2F-4A16-A381-3E560C68BC83} to both of your registry locations, given them a value of 1, & restarted my Windows 10 (V. 2004). External drive (S:)
    is still listed under “Devices and drives” plus twice on the navigation pane. Obviously this no longer works. I work in the registry all the time and am very computer literate. Any other suggestions?

    • @Eddie: I tested the “nonenum” registry edit as in the article. It worked perfectly in Windows 10 v2004. FYI. It’s still valid in October 2020.

  4. Your locaton in the registry is incorrect. If it’s a 32-bit system:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\DelegateFolders
    If it’s a 64-bit system, do the above plus the following:
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\DelegateFolders
    In both locations under Delegate Folders, delete:
    {F5FB2C77-0E2F-4A16-A381-3E560C68BC83}
    Then restart File/Windows Explorer by doing the following:
    1. Open Task Manager by right clicking on the Taskbar.
    2. Make sure “More Details” is selected.
    3. Scroll down past ‘Apps’, past ‘Background Processes’, and then almost at the end of
    Windows Processes you will find Windows Explorer (or File/Windows Explorer).
    4. Right click on it and select ‘Restart’.
    When you go back to the Navigation Pane, the duplicate of your particular drive should be gone.

    • @Eddie: No. There are at least 2 methods to remove the duplicate drives in Explorer. Yours is one method, mine is another. Either one works in all versions of Windows 10 (the current version is 2004).
