無料オンラインCPIOから7Zへのコンバーター

A file compression format that is created in a corresponding tape archiver. It’s still used in the Linux version 2.6 kernel and the 'pax' archive installer from Apple. The archive contains header information with data about access privileges, the owner and time of creation. It was created to store back-up data on tape drives and other tape devices. These days Oracle developers deliver much of their software in CPIO format.

This format works based on the main compression algorithm LZMA. It was originally used in 7-Zip archives. Other compression algorithms can be used in 7z since this format has open architecture for developers. It has a high compression coefficient. The encryption algorithm is AES-256.
