How do I download a RM game?

I got an RM made game, but when I try to open it with winRAR, I just get a list of all the maps and sprite images and whatnot. I know that this isn't technically an RM problem, it's really winRAR, but could you help me out anyway?

well, when you extract an RM game, it'll do like that. But there's also an Orange Icon, that is the rm icon you need to run to start playing it. (in case of the rm XP game).
If it is white, it is rmVX game. If it a sword icon, its rm2003. You need the RTP of the correct RM to play the game.

If it's XP/VX there's a game.exe
if it's rm2k/3 it's rpg_rt.exe or sometimes they rename it.

Just open the exe file and don't forget to extract all of the files in a folder.
