I was looking into Linux, maybe installing it. But i want to get a few info before I do. I know there are one click type installation of programs etc. services but you usually have to pay for a subscription of some sort. But what if you don't want to subscribe to those type of things, or you download something that isn't on that list. Then how would you install it? The file names are usually in the form of TGZ which I believe is tar gunzip. Isn't there a simple way of installing these little stuff like windows so-call setup.exe?
