Some Bad news and a good question for you...

BAD: The spider can take over 20 minutes to search every directory on the computer!

QUESTION: Can the batch file do this?
*. Check to see if they changed the default directory
2. If the directory has been changed ask them to type in the directory location of the .exe ?
*. After they type it in once the .bat will create a shortcut on the desktop pointing to the program and will delete itself.
