What is a CPIO file?

A .CPIO file is a CPIO Archive file.

Files with file extension .cpio are archive files created on a Unix system. An archive file is basically a batch of files bundled into a single file for easier storage and distribution. An "extraction" tool is needed to restore the files to their original state.

CPIO files are usually created by the Unix command-line tool of the same name: cpio. However, the archives can be extracted by several other tools, also on non-Unix computers.
