WinZip is a straightforward zip and unzip utility that includes built-in support for popular Internet file formats: TAR, gzip, UUencode, XXencode, BinHex, MIME, and Unix compress. ARJ, LZH, and ARC files are supported via external programs. An optional wizard simplifies unzipping and installing software in ZIP files. WinZip 6.3 features automatic, built-in disk-spanning support for multidisk ZIP files. Other enhancements in the new version include better Windows 95/NT shell integration, so it is easier to zip and unzip directly from the Explorer, and improvements to the built-in WinZip Self-Extractor Personal Edition. WinZip also includes an interface to the freely downloadable Internet Browser Support add-on, which lets you download and open ZIP files from the Internet with one click via Microsoft's Internet Explorer or Netscape Navigator. This new version of WinZip is a free upgrade for all registered users.
