RAR is a kind of compress format. You can compress a folder with many subfolders and files in a RAR file which still remains the file structure with smaller volume in fast speed. When you send files by email, you'd better make the files as a compress format, as the recipient can download the attachment by downloading one file. Before RAR file, people use ZIP file. But RAR has smaller volume and faster speed in extracting than ZIP file. Though Windows 7 and Windows 8 already support to extracting ZIP file, people are still fond of using RAR files. You need to install a software to open RAR file, either "WinRAR" or "7-Zip" can finish the work.
