Hi to all, I read some excellent reply in this forum which give me the hope to ask for help. I want to modify a .bat file and burn it to a DVD that can install the game to hard drive but will ask for to chose a drive. I don't want it to be installed always to c drive and don't want to copy it to a drive and then install. The code I have that can install the game where the folder is and then delet the setup files. After lots of reading I know how to use the code to copy from DVD to c drive and then delet setup files. But now I want to go one step advance which is chosing a dive in .bat setup. I know there are some option code which have to be written in 1,2,3 format, but I don't know how to convert that to chose drive.. I am posting the code that i have, which install the game in same folder, run regedit and delet the setup files. @echo off cls title GAME cd main cls 7z x models.7z del models.7z cls 7z x main.7z del main.7z cls 7z x the_rest.7z del the_rest.7z del 7z.exe cd .. 7z x the_rest.7z del the_rest.7z del 7z.exe cls regedit setup.reg cls Pls help to me with the rest.
