Re: Best way to discover resource forks?

As far as I know, there is no Cocoa way to specifically check for the 
presence of a resource fork.  I'm not sure how quick FSIterateForks 
is, but you may be able to get by using FSGetCatalogInfo() and asking 
for kFSCatInfoRsrcSizes in the whichInfo field.  If you're 
enumerating a directory, you can also get a speed boost by using an 
FSIterator and the Bulk variation of this function.  A Cocoa 
implementation of this latter approach can be found here 
(UKDirectoryEnumerator):  http://www.zathras.de/angelweb/sourcecode.htm
