A compressed file is any file containing one or more files or directory that is smaller than their original file size. These files make downloading faster easier and allow more data to be stored on a removable media. Common compressed file extensions are .ZIP, .RAR, .ARJ, .TAR.GZ, and .TGZ. Below is a larger listing of the different compressed file extensions you are likely to come across when working on a computer.
