Um, files don't contain a data structure.  You read data in from files into=
 a
data structure (array, hash, etc..).

Um, this is same concept as any language.

1.  Open file
2.  Read into data structure

Iterate over the data structure and use one of the IO methods:
puts, print, printf, etc..

Why post this to a Ruby list?  This is a kdevelop/qt item and needs to be
post to an appropriate list.

Need to gain more about basic principals.  If you don't understand reading =
of
files and such same goes for getting the directories contents.

Please see the programming ruby to clear up many of the falsities in this p=
