How do i open a rar file?
Windows computers don't have a baked-in ability to open RAR files. If you double-click or double-tap a RAR file without having specific software installed to open it, you'll probably see one of the following messages: "Windows cannot open this file" or "How do you want to open this type of file (.rar)?".
RAR is actually the native format of an archive program called WinRAR, in my opinion, the best is the 7-Zip program.
