well he does have a point
I mean there is such a thing as google
and I'm sure when you search for the term "rar" the first result is the link to winrar (wait lemme try, yep i'm right (as always).

so next time you have a file problem the least you can do is search the extension on google and see what comes up.

btw you'd be amazed to see what you can do with google.
for example you don't need torrents limewire or any other filesharing application
google can do it all.
or you can get a live feed of a lot of security camera's right there from google.
the list goes on and on
