WinZip is a straightforward 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. ARJ, LZH, and ARC files are supported via external programs. An optional wizard simplifies unzipping and installing software in ZIP files. New features in WinZip 7.0 include the ability to create self-extracting files that span multiple disks, the ability to print a list of files in a ZIP, sizable and sortable columns in the main window, easier configuration using a tabbed dialog box, an improved install feature, optional support for IE 4.0-style 'one-click open,' and a configurable toolbar with 21 new button graphics. Note: The new graphics require the Windows Common Control Library 4.71 or higher. It is included in Windows 98 and IE 4.0. This download is a free upgrade for all registered users. It is a 21-day evaluation version for nonregistered users.
