Xar

The Leopard news of the moment is that Xar will be baked in. Xar, or eXte ible ARchive format, is just what it sounds like, a new way to compre files. You're thinking, 'Aren't there lots of ways to do this already?' Yes, but as this page entitled 'Why xar is interesting' explai Xar has some big things going for it. Firstly, it kee metadata (like file type, MP3 data, and the like) in a separate file so you can tell lots about a compre ed file without having to uncompre it. It also compre ed each file separately, so if you Xar a folder each file is compre ed separately.

Xar is already available for download, if the more technical amongst you would like to take it for a in.

Pretty neat.
