In 1999, ALZip is originally developed as an internal application at South Korean software company EST soft. It is an archive and compression utility designed for Microsoft Windows to address their employees frustration with using English interface in WinZip. It can unzip 40 different file archives and can ZIP into eight different file archives like TAR, EGG, ZIP and many others. It runs in Windows 2000, Windows XP, Windows Vista with 32/64 bit, and Windows 7 with 32/64 bit. ALZip has the ability to set password using AES-128 bit or AES-256 bit encryption; span a ZIP file into ZIP files; merge spanned files in one, restore corrupted files; check for virus using your anti-virus software; create self-extracting archive (EXE) that enables users to open the archive without installing file compression program; check errors in ZIP files; and command line functions for expert users. ALZip is a shareware and is available in English, Korean and Japanese language.
