AutoZip

From Innerlab Productions:

AutoZip is a file decompression tool that will let you extract ZIP files directly from Netscape Navigator and Internet Explorer. If the ZIP file contains a setup program, AutoZip can extract the archive temporarily and run the setup file. From within the AutoZip interface, you can view files with the internal text file viewer. You can also run programs and open documents within the ZIP file simply by double-clicking.With AutoZip you may also create zip files and self-extracting archives. If you are new to this, you can use the Create Zip File Wizard. AutoZip also supports password encryption of your zip files. A pedagogical help file that teaches you how to use AutoZip is included.
