More Files is available to help with developing file and directory 
routines. Go to 
<http://hyperarchive.lcs.mit.edu/HyperArchive/SearchForm.html> and 
search 'More Files' for one place it is available.
Also you can search for technical information at the Apple site

 From the More Files read me:
----------------------------
What is MoreFiles?

MoreFiles is a collection of high-level routines written over the 
last couple of years to answer File Manager questions developers have 
sent to Apple Developer Technical Support and to answer questions on 
various online services and the internet. The routines have been 
tested (but not stress-tested), documented, code-reviewed, and used 
in both my own programs and in many commercial products.
