How to fix error error-same-drive in Windows 11

Solution Steps

1. 1 Open Command Prompt (Win+R, type 'cmd', press Enter). Type 'subst' and press Enter to see current mappings. Note the drive letters in use.
2. 2 If you are trying to map a drive to a folder on the same drive, you need to choose a different drive letter that is not the same as the source drive. For example, instead of 'subst C: C:\Temp', use 'subst X: C:\Temp'.
3. 3 If you specifically need to use the same drive letter, consider using a symbolic link instead. Open Command Prompt as Administrator and type 'mklink /D C:\LinkName C:\Temp' (replace LinkName with a name for the link). This creates a directory junction that does not require a separate drive letter.
4. 4 Alternatively, you can map a network drive to the local folder using 'net use' with the \\localhost\C$\Temp syntax, but this requires network sharing to be enabled.
5. 5 After making the change, verify the mapping by typing 'subst' again or checking File Explorer.
