Grab The Unarchiver free from the Mac App Store.While most archives these days are made as zips, you never know when you’ll encounter one of the more unusual file formats, so instead of getting stuck with a useless uncompressable archive, extract it all with Unarchiver. Unarchiver is a free download and should be considered a must-have utility for all Mac users. There are a variety of options for managing the archives as well, you can set Unarchiver to always extract to a specified folder, trash the original archive after extraction, open the extracted folder immediately, adjust the modification time of the created folder, and a few other handy adjustments. Once Unarchiver has been affiliated with the archive formats of your choice it will automatically launch and extract the files if you come across them, the integration is completely seamless much like the Macs default utilities for decompressing files.
