CPIO files are used in various software applications, primarily for archival purposes, and they require specific file formats to open and use. The term 'CPIO' stands for the 'copy in, copy out' method that is used to describe the archiving process. The primary function of CPIO files is to store multiple files and directories inside a solitary file, usually for backup or transportation purposes.

CPIO file formats are incredibly versatile and can be used in various applications. The typical way to identify a CPIO file is from its extension (.cpio). This format is often used by embedded systems developers for root filesystems, for the exchange of files between older and newer systems, and for the creation of initramfs (initial RAM file system) archives used during Linux startup procedures.
