RAR is a proprietary file format for data compression and archiving package. When we want to send some files to others with the attachment, we often compress the files into one RAR file for smaller size and faster transmission speed. When we receive the RAR file, we can use WinRAR to decompress RAR file free, which is very convenient for our work. But all we should know that, if the RAR is set password by others, we can’t open it with WinRAR, in this case, you should use RAR Password Recovery to recover RAR password first. Then you are able to view RAR files with WinRAR.
