VBA to open .bat file

The file path leads onto the m drive. Should I change it to "cmd.exe/m" instead? This doesn't execute it either, but it is opening the command window permanently.

Sub Belfry()
    x = Shell("cmd.exe /c M:\My Folder\Karen Postiglioni\JP\CSV Files\salesforce.com\Apex Data Loader 22.0\cliq_process\Update_Test_FNMA.bat", 1)
End Sub

This is the error that I'm getting from the command line:

'

CMD.EXE was started with the above path as the current directory.
