Hello, I have created a batch file that amongst other things allows my users to backup up all of their My Docs to an external hard drive. The process is a two fold. 1. there is an install.bat which copies some support files to the system32 folder, copies the actuall backup.bat to the C: drive and crates a shortcut on their desktop, it also creates folders on the external drive which will be used by the backup.bat My problem is that I don't know which letter drive the external drive is going to be!! I've already set a variable for the letter drive but I have to hard code it (set drive=G )So what I would like to do is somehow ask the user what letter their external drive is and then use that to go in to my backup.bat and replace my G in this case for whatever their input is. HELP!! Thanks in advance. AJ

Try using %~n1, This should set the variable to the first argument passed on the command line. So for your example you'd use: Install.bat G:\ Got a problem? give www.support.com a try

set /p drive=What drive letter is your backup drive?

Thank you both!! Set /P is exactly what I was looking for. :-)
