I did not yet study the implementation of the File class, but the methods look very similar to the Java "File" class.
http://download.oracle.com/javase/6/docs/api/java/io/File.html

If this is it the case, then I'm inclined to copy-paste some portions of the Java "File" documentation... I'm not native english writer so this doc is far better than the doc I could invent myself.
No objection ?
