Are you in need of a robust yet quick archive opener that can handle a multitude of file types? Zipeg for Mac is all this and a little more. It can handle .zip, .rar, .7z, .z, .tar, .gz, .tgz, .bz2, and other exotic archive types, and it particularly excels at large archives.
With Zipeg for Mac you can see the files contained in the archive and manually select the ones you wish to expand, leaving unselected files unexpanded. By processing only what matters to you, less space is wasted on your hard drive and you wait less time as the archive opens. This is of course particularly handy for large archives or ones that contain an unexpectedly large number of small files. Another function where Zipeg will beat the competition in is its ability to sometimes extract files from archives that are partially damaged. Most software will only successfully decompress archives if the whole process didn't cause any error, even if some files were OK. Of course, it also handles split archives. The only downside to this software is that sometimes you just want to double-click an archive and expand it. In those cases, it will not be the most appropriate choice, given the fact that two actions will be required instead of one. First you'll need to click your archive, which directly opens Zipeg's interface, and only then you can launch the decompression action.
Zipeg for Mac seems to be a very handy tool that is both free and packed with better features compared with its competition. Anyone regularly using archives, both small, large, or partially damaged should keep a copy of this software on their hard drive for occasions where classic expanders are struggling to get things done.
