I am trying to open the resource fork for every file on a disk and extract
information from the 'vers' resource.  I currently have a recursive scanning
routine assembled that scans the disk for all the files.  As the scan is 
running I want to open each file and extract the info.  I am using
OpenResFile and giving it each file name as I get it form the disk.  This only
works  for the files in the system folder and fails for all the rest.

I have heard that the concept of the working directory is important here and
that I must make the folder I am searching the current working directory for
the OpenResFile to work.  I have checked into using PBOpenWD but I do not
understand it!  I do not clearly understand the difference between ioWDDirID,
ioVRefNum and ioWDProcID.  The confusion results between using vRefNum for the
volume and working directory.  Now I may have this working directory idea 
completely wrong and it is not needed to make this thing go.  

Whatever, I would like to search the entire disk for say all the files of type
'APPL' and extract info form the 'vers' resource.  I am using Think C 4.0
and am an experienced programmer.  I need a guiding hand to make this come
clear.  If anyone has a clue please send me the secret.

Mucho Thanks

Andy
