Convert to CPIO Online Tool.
A CPIO file is an archive file used by various programs, most notably the Linux operating system. A CPIO file typically contains one or more files that have been compressed and bundled together. The contents of a CPIO file can be extracted using a program such as the cpio command. CPIO files are often used to distribute software packages or to back up files. They can be created using various programs, such as the cpio command or the tar command. The file format is relatively simple and well-documented, which makes it easy to write programs that can read and write CPIO files. There are two main variants of the CPIO file format: the new format and the old format. The new format is the more common one and is used by most programs that deal with CPIO files. Some programs still use the old format, but it is slowly being phased out.
