-[[CrLZH]] (often  referred to as just "LZH", but not to be confused with the format used for [[LHA|.lzh]] files) was a method of compressing single files used on [[CP/M]], devised by Roger Warren in the late 1980s. It came later than [[Squeeze]] and [[Crunch]] and generally achieved better compression than those formats. LZH files occurred standalone and as members in [[LBR]] archives. The underlying compression is based on that used by [[LHArc]].
