Yes, we know since Windows XP, you don’t need a 3rd-party unzip program to unpack zip files. But what if you download a RAR file or Gzip file or some other kind of compressed (zipped) file? You’re kind of stuck, because Windows won’t recognize them. So you’ll have to searching for a program to open these other types of compressed files because Windows decompression (unzipper) is limited to a few file types, like zip and cab.
So doesn’t it make sense to install a free program that will unzip any kind of zipped file you might download and associate it with all compressed formats? Of course. It’s good advice. And that’s why we’re recommending 7-zip – a free and unique decompression utility that unzips any kind of zip file easy and automatically. All you have to do is install 7-zip and associate it with all types of compressed files (zipped files) and let 7-zip handle unzipping them. To do this, download 7-Zip from www.7-zip.org and install it. Then open it, click “Tools” and under the “System” tab you’ll see all 35 types of compressed files that 7-zip will open. Press the “Select all” button – then click “Apply”. 7-zip is now associated with every kind of zipped file you’re ever likely to encounter. So the next time you download a file with an RAR extension – you won’t get the “Select the program you’d like to open this file with….” dialog. 7-zip will open RAR and 34 other zipped file types (including zip and cab).
