MacHacha is a utility to split and join files using several common cross-platform formats (windozee, mac, unix), such as hjsplit, hacha, fastsplit or winsplit. Since version 1.1, also supports joining-uncompressing RAR files. NOTE: Pre-Panther users who can't run current version, can pick here a working one: http://homepage.mac.com/julifos/soft/machacha/machacha_carbon.sit
