What is a cpio file?
A CPIO file (Copy In/Copy Out) is an archive format commonly used in Unix-like operating systems. Originally developed for backup purposes, CPIO creates archives that can store multiple files and directories while preserving file metadata, permissions, and directory structures. Unlike some other formats, CPIO can handle special file types and has the ability to skip corrupted sections during extraction.
CPIO is notably used in Linux systems for creating initial ramdisks (initrd) and RPM package management. Its streaming nature makes it particularly suitable for tape backups and system installations, though its less commonly used than TAR for general-purpose archiving. When creating CPIO archives with ezyZip, date information is not included and empty directories are not added to the resulting archive file.
