MacItBetter (http://macitbetter.com/) has announced BetterZip 3, an update to their archiving solution for Mac OS X.
The utility lets you peek inside archives without first extracting. You can explore the contents of archives and preview files inside using a preview sidebar or even Quick Look. With BetterZip you can compress or extract files with drag-and-drop. Update, move, rename and delete files inside archives as if you were working with normal folders. Version 3 now supports winmail.dat files, DMG files, and ePub files.
BetterZip 3 requires Mac OS X 10.9 or later. A trial version can be downloaded from MacItBetter online and is fully functional for 30 days. A single user license costs US$19.95; discounted upgrades are available for $9.99.
