CPIO (Copy In/Out) is a Unix archive format that predates TAR and was part of the original Unix distribution. The cpio command copies files to and from cpio archives, with three operating modes: copy-out (create archive), copy-in (extract archive), and copy-pass (copy files between directories). CPIO is notable for its role in the Linux boot process as the format used for initramfs (initial RAM filesystem) images.
CPIO archives store files with their metadata including permissions, ownership, timestamps, device numbers, and inode information. The format has several variants including old ASCII, new ASCII (newc), and binary formats. Linux initramfs images are CPIO archives (often compressed with gzip or lz4) that the kernel extracts into a RAM-based filesystem during boot. RPM packages use CPIO as their internal archive format for the actual files being installed.
CPIO is natively available on all Linux and Unix systems via the cpio command. On macOS, the bsdcpio command is available. 7-Zip on Windows can extract CPIO archives. The libarchive library used by many modern archive tools supports CPIO. The format is most commonly encountered when working with RPM packages, Linux kernel source trees, or initramfs images.
CPIO is a specialized Unix format primarily encountered in system administration and Linux development contexts. Converting CPIO to TAR, ZIP, or 7Z makes the contents accessible with standard archive tools. LetsConvert handles CPIO conversion to all major archive formats while preserving file structures.
