Anyone knows how to unrar a zip without installing programs like 7zip or winrar?
I'd say, just install it. There "might" be a way to do that but if the procedure would take too long hence the installation of those compress/decompress programs.
get a portable copy of winrar or 7zip. the files would be on your computer but it's not really installed.
^---- agree. People created portable apps so you can put it on a thumbdrive
BTW, why is this under health? Is installing winrar causing you heart attack?
what the world.. thought you can unzip stuff straight out of the box with winxp. what os have you got?
