[Pythonmac-SIG] FTPing a mac file - loosing resource fork?

[Sean Hummel]

The majority of the problem you are having is likely due to the fact 
that the file on the server was uploaded as a binary file.  Not using 
one of the Macintosh flat file formats.    (i.e.  HQX or MacBinary)  
Thus the file on the server doesn't have a resource fork.  

When you upload the file, upload it as an "HQX" file, and use the 
Python "binhex" module to turn it back into a Macintosh file, after it 
is downloaded.

As far as automatically "Unstuffing" the file, there are many routes, 
you could create an Applescript and tell "Stuffit Expander" to 
decompress the file.  

Or you could use the AE module to send appleevents directly to the 
Stuffit Expander module.
