What is a 7z, rar, zip file?
When u download a file from they are usually compressed ones. It means that you need to extract the content to be able to use/see what's inside.

We use to pack the files in 7z format cause it has a better ratio compression, and that means the file will have a smaller size. Anyways this format can be also opened with winrar if it's the program you use to deal with your compressed files.

We recommend to install and use 7zip from to manage your compressed files (7z, rar, zip, ...), cause it's a free program and works perfect.
