LZARI, or LZARI.C, is a file compression utility developed by Haruhiko Okumura. It was distributed as source code. It uses LZSS-flavored LZ77, combined with arithmetic coding.

In his "History of Data Compression in Japan" document, the author writes "There were several versions of LZARI; some of them were slightly different."

Format details

Files have a minimal header, containing the uncompressed file size. The format is not portable, because it differs depending on the compiler's in-memory format of the "long" data type.
