How do you clear some memory from C drive when using just the command prompt. I can't remember how to do it! I tried to install GNU C++ and I had to put some commands into autoexec but things went wrong and now can't bootup to windows or access any files. It looks like that I will have to re-install windows but I have to clear some memory from C drive to do this because when i tried to install windows again it said that I have not enough space on C drive. What I want to clear is the existing windows98 programme and other stuff but not anything in my own files or poss my internet connection. So please can someone tell me how to do this step by step.
