Postup řešení
- 1 Press Windows key + R, type 'cmd', and press Ctrl+Shift+Enter to open Command Prompt as Administrator. This ensures you have the rights to manage drive joins.
- 2 Type 'mountvol' and press Enter. This lists all mounted volumes and their junction points. Look for any entry that shows a folder path (like C:\MountedFolder) that is no longer valid (e.g., the drive is missing).
-
3
To remove the invalid junction, type 'rmdir
' (e.g., 'rmdir C:\MountedFolder') and press Enter. This removes the folder junction, clearing the error. If the folder contains data, you may need to move it first. -
4
If you need to recreate the join correctly, use 'mountvol
\\?\Volume{GUID}' (replace with the actual volume GUID) to reattach the drive. - 5 Restart your computer to ensure all changes take effect. After reboot, verify the error is gone by accessing the folder path or running the application that previously failed.
