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.
Zipeg is software that was developed by Leo Kuznetsov, and this application is known as a file decompression tool that can open ZIP and RAR files. This tool runs on both Windows and MAC operating systems, and with this program, users are able to preview their files before extracting them. Zipeg features a user interface that is open source and Java-powered. This tool also has the ability to detect filenames, even if they are in different languages, and can translate many foreign languages into Unicode. Zipeg is also able to read EXIF thumbnails by using these thumbnails as item icons and "tool tip" style preview. Aside from the preview feature, Zipeg also comes with an "Options" button, and this allows users to select the files they want to open. Zipeg makes it easy for users to extract compressed files, and since they can view the files first before extracting them, they can freely choose the file they want to open and extract only the files that they need.
