iZIP Archiver is an archive manager for Mac OS. Its strength is supporting all the most widely used archive formats (ZIP, ZIPX, RAR, TAR, TAR.GZ and 7ZIP) in an easy-to-use package. iZIP Archiver installs quickly and easily.
With iZIP Archiver, all archives appear as removable storage, so you can save directly to them, instead of having to move a saved file later. You can drag and drop files into and out of the archive. You can add encryption to an archive if you want to secure it, requiring a password to access the contents. The interface is simple. To create an archive you can use the iZIP Archiver wizard, which walks you through the steps to create an archive and add security. You can also set the sharing level and have an archive shared and accessible through a Web site (account required).
iZIP Archiver is a free app and since it handles almost every file archive format you'll encounter, it's a tempting download.
