Welcome to StuffIt Expander® 8.0

StuffIt Expander 8.0 is a utility designed to Expand (give access to) almost any compressed, archived, or encoded file that you receive, or download from the Internet. In many cases StuffIt Expander will be used automatically by your web browser to expand files files immediately after they are downloaded, but you can also Expand files by dragging and dropping either onto the StuffIt Expander icon or into the "Drag and Drop" window that appears when you launch StuffIt Expander. This kind of manual expansion is needed when your Web browser fails to call upon StuffIt Expander, or when the file comes as an email attachment or other non-Web source.

What's New in Version 8.0

StuffIt Expander version 8.0 introduces support for two new files formats, .cab and .yenc. Files with a .CAB extension almost certainly come from a Windows based PC. These files are archives that can contain any number of other files and folders. Files with the .yenc extension are encoded using the new yEncode method. Files of this type are becoming more popular on Usenet (or newsgroups) that host Windows binary files.
