WinRAR: "Unknown method"

With "WinRAR" you can pack and unpack archives. Under certain circumstances, errors can occur.

• Compression: When compiling the archive files, the content is compressed. If errors occur, it is impossible to unzip the file. WinRAR reports either an "Unknown method" or "Unknown compression method" error.
• Data transfer: If you download an archive from the Internet and the error occurs, then it is very likely that the files are damaged. If a file contains errors, WinRAR cannot open the archive.
