Netzip is a plug-in for Web browser s that allows you to view the files within a zip file from within your browser without the need to launch an external application. Netzip lets you create a zip file archive (including one that spans disks). It also lets you choose a compression algorithm when you create an archive. You can decompress and extract from ARJ , Lharc (LZH, LHA, LHZ), Z, GZ, and TAR (TAZ, TGZ, TAR.Z, TAR.GZ) files. Netzip also lets you temporarily "check out" files within a zip file and run installation utilities.
