You can create Zip Files, using the standard WinZIP utility on Windows. In Internet Explorer Microsoft Internet Explorer supports an alternative to zip files called cabinets.
Cabinets can include .class files, images, and audio clips.
Cabinets are not limited to Java files, however. IE supports many other kinds of executable content, and any of them may be packaged in a cabinet file. Cabinets may also contain compressed data, allowing you to download code quickly. The data compression, along with the fact that you can group many different file types in a cabinet, make cabinets an attractive alternative to zip files. The biggest disadvantage to cabinets is that they are currently available only under Internet Explorer.
