OK, that rather surprises me - why haven't Apple done a decent file
copying system in Cocoa yet! Maybe I should file a request.
So, I downloaded MoreFilesX. It's readme says quite a bit about the
HFD+ APIs. Am I right in thinking that the code will use the HFS+ if
suitable, but that it will still work for non-HFS+ operations?
Assuming that this is OK, I've had a look at the command FSCopyFork -
I assume that's the one you meant? However, I know very little of
this Carbon style stuff and so I'm a little confused :(
The function requires a source reference number, a destination
reference number, a copy buffer, and a copy buffer size.
I understand the first two and how to sort them out (I think!), but I
haven't a clue where to start with the buffer stuff. Any chance you
could nudge me in the right direction? I've googled around, but not
found any examples yet.
Mike.

There really isn't a Cocoa option. You'd have to write a lower-
level copy
function yourself, probably having it use
performSelectorOnMainThread to
post updates back to the UI. Fortunately, the myriad details you'd
need to
take care of when copying a file are handled in sample code. Look for
MoreFilesX, specifically FSCopyObject...
