Hi, I need a little help with Downloads... My computer wont read Rar files... is there an app i need to download? if so could you provide a link too it?

WinRAR

Enjoy.

for som reason, it doesnt do anything... i installed it and went to watch a video and it wont do anything...

Well if you have the "whatever.rar" just right click on it.
Then there should be some options (with the icon of winrar, those books or what ever).
One says "exract here" or something like this, use this on.
Based on the computer of yours and the file size it will take sometime.
After you did so there should be a new file somewhere at the current path.

btw I recommend 7zip, this is also a compress program but the big advance is that it makes use of more than 1 core.
