The cpio file type is associated with Unix-based systems and represents a format used for archiving and compressing files. The name "cpio" stands for "copy in, copy out," reflecting the method by which files are gathered into an archive or extracted from one. This format supports various compression methods and is commonly utilized for creating archives in backup processes, distributing packages, or consolidating files for easier transfer. A cpio archive can contain multiple files and directories, preserving their file attributes.
A compressed file format associated with GNU Zip (Gzip) that uses the DEFLATE compression algorithm, a combination of both the Huffman coding and the Lempel-Ziv (LZ77) codec.
