Opening Files in OS X

[Jim Biancolo]

Thanks again Monte, I've done the reading, and I have a follow-up question, 
if you don't mind (or if anyone else has advice on this).

My understanding is that Mac OSes use fileType to determine if a file 
"belongs" to an application.  Furthermore, it seems that the OS prevents my 
app from opening files that don't belong to it (judging from the docs and 
the way my app is currently behaving).  So what I need to do is set the 
fileType when my app saves a file, and then the app will be able to reopen 
that file later.

Is that right?  If so, what happens if a Windows user of my app creates a 
file and tries to share it with a Mac user of my app?  The docs suggest 
that Windows ignores fileType, so will the Mac user be prevented from 
opening files created by Windows users?

These files are just text files that have a *.upf extension in Windows.

Thanks!

Jim
