I just downloaded this game last night, so sorry if this is in the wrong place, but I'm having trouble figuring out how to use a .rar skin. I have winzip which I've used to unzip the file. I added it to my skins folder and dragged it onto osu but I keep getting an error message that says "Sorry, osu doesn't know how to deal with this file type." I've looked on the forums for a more detailed guide on how to install .rar skins but I can't really find anything that helps.
This is the skin I'm trying to download btw if it makes a difference: t/181251
