I notice that in the "detailed folders" listing, an app bundle appears  
as follows (for example):
Revolution.app,136,1535180800,1035608180,1068205493,1075788371,0,501,80, 
777,????????

Note it is in the folder list, not the file list, has question marks  
for creator/type and a ".app" suffix on the name. I am assuming this  
will provide reliable identification.

When you encounter a folder of this nature, initiate directory walker  
for that folder alone (this is within your normal walk process - you  
will need to add this code), add up the components, and list it under  
the app bundle name with ".app" stripped. OK?

Well, I think it should work :-)
