The Leopard news of the moment is that Xar will be baked in
. Xar, or eXtensible ARchive format, is just what it sounds like, a new way to compress files. You're thinking, 'Aren't there lots of ways to do this already?' Yes, but as this page entitled 'Why xar is interesting
' explains Xar has some big things going for it. Firstly, it keeps metadata (like file type, MP3 data, and the like) in a separate file so you can tell lots about a compressed file without having to uncompress it. It also compressed each file separately, so if you Xar a folder each file is compressed separately.
Xar is already available for download
, if the more technical amongst you would like to take it for a spin.
