Sorry Bubba, but this thread is becoming ridiculous. Creating folders is not witchcraft, and is considered basic computer knowledge, i think. Creating folders is actually the easiest part of playing old DOS games with DOSBox, so i don't see this thread ending soon. I don't think we're here to give you a "Computers for beginners" primer. Don't you have someone to help you with that stuff, a friend or a relative maybe? That would be much more efficient than trying to solve multiple problems at once, in blind flight, like you're trying now.
Anyway, maybe this helps: you just need a folder to mount as a c:\ drive in DOSBox, any folder. You could create "c:\dosgames" on your host system, and mount that folder in DOSBox. The name or location of that folder doesn't matter at all, because it will simply become your c:\ drive inside DOSBox after mounting it. If you want to create a folder inside a folder, first create the top folder with Windows Explorer, then click on that folder with the mouse, and create another folder. Using a simple folder structure (like the "c:\dosgames" example above) might actually be easier for now. If you're using Windows Vista (i'm not sure, you've mentioned "VISTA" in one of your posts, but completely out of context), the whole thing becomes a bit more complicated, as you have to create the folder in a place where you have access rights with your Windows user account. I don't use the POS that is Vista, so i'm not quite sure where such a place might be. A workaround would be to logon as an Administrator on your machine, that would give you access to any folder on your harddrive.
