I'm pretty new to Cocoa; I have been reading though the developers documentation for quite a while. I just can't seem to figure out the whole plist thing, so I have a few simple questions ... 1. What exactly is a plist? 2. What kind of things are they used for? 3. Whats the difference between the plists written in curly braces and the plists written in XML format? 4. If there isn't a real difference then can the plists be interchanged i.e. could i change a curly brace style plist to an XML style plist? Thanks much guys, Mark.
