Version: 1.5.86
Impressive speed! I would like to know why Archive Utility can't open .rar files but, so far, I had to search a smart alternative: FOUND! Compression, DEPRESSION (the world 'decompression' could be funny if it was not used seriously, a tragedy of the recent fall down of the mastering of the mother language of some folks!!!) in a snap! Maybe the user interface could be rethought a bit but, seriously, WHO CARES when all works so fine and quickly and it's almost never needed?
