WinZip is a straightforward, fast, and easy-to-use zipping and unzipping utility that includes built-in support for popular Internet file formats such as TAR, ZIP, UUencode, XXencode, BinHex, MIME, and Unix-compressed files. Older ARC, ARJ, and LZH files are supported via external programs. In version 8.1, enhanced Explorer integration adds more options to the Explorer context menu and allows you to unzip several archives at once; compress several small ZIP files for easy sending via an e-mail attachment or as an alternative to disk spanning; a new Quick Pick taskbar icon gives you instant access to WinZip and recently used ZIP files; WinZip Wizard enhancements allow you to run installation files included in ZIP archives and extract files from split ZIP files and multiple disk ("spanned") ZIP files; and support for Windows XP allows WinZip to run as a native Windows XP program with no need to set the compatibility mode.
