Winmount: Need Help W/ Batch File!

Hi! I have WinMount on two computers, but on one, it doesn't work properly: I can't mount an archive file. So, I'm using a batch file to decompress a file, use SUBST to mount the folder as a drive, wait until I'm done then recompress if necessary and clean up. The batch file follows:

Code:

@echo off
::echo %1
echo Mounting your WinMount drive now...
::Change the path in the next line to the one of your WinMount installation:
md "C:\MyPrgs\WinMount"
md "C:\MyPrgs\WinMount\%~n1"
"C:\Program Files\WinMount\WinMount.exe" -E %1 "-o:C:\MyPrgs\WinMount\%~n1"
subst z: "C:\MyPrgs\WinMount\%~n1"
pause
subst /d z:
choice /m "Save modifications to WinMount archive?"
if errorlevel 2 goto exit
"C:\Program Files\WinMount\WinMount.exe" -C "C:\MyPrgs\WinMount\%~n1" "-o:%~1"
:exit
rd /s /q "C:\MyPrgs\WinMount\%~n1"
pause

The problem is that, when I use it, I get an extra folder in the path, meaning the path contains an extra entry of the same name. What am I doing wrong? Is there a way to get WinMount to work properly, so I don't need this file? BTW, how do I run Explorer from a batch file?

 

md "C:\MyPrgs\WinMount" remove this line
md "C:\MyPrgs\WinMount\%~n1"

explorer
or a specific directory
explorer "C:\Users\YourName\Documents"
