Thanks for reply!

Crrently in code used NavGetFile (it's look like very old dialog
function...??)

>From FSSpec I get the only full path, but not file name:
FSRef fsRef;
CFURLRef URLRef;
OSErr oserr;
CFStringRef StringRef;
oserr = FSpMakeFSRef( &documentFSSpec, &fsRef );
URLRef = CFURLCreateFromFSRef(kCFAllocatorDefault, &fsRef);
StringRef = CFURLCopyFileSystemPath( URLRef, kCFURLPOSIXPathStyle
);
CFStringGetCString( StringRef, (char*)&theFile->FileName,
sizeof(theFile->FileName), kCFStringEncodingMacHFS );

Ok, I'll learn this issue later...

Thanks!

You should use the newer Nav Serv APIs. Avoid any API that uses FSSpecs.

No, it's not VERY old. It's merely passe. StandardGetFile is very old.
SFGetFile is ancient.

Another thing you can do with a CFURLRef is extract the components of
its path as strings. CFURLCopyLastPathComponent() is the one you want
for just the leaf name.

Thanks for reply!
OS: 10.3.9+
There in code used only NavGetFile function.
I've used some code:

FSRef fsRef;
CFURLRef URLRef;
OSErr oserr;
CFStringRef StringRef;
oserr = FSpMakeFSRef( &documentFSSpec, &fsRef );
URLRef = CFURLCreateFromFSRef(kCFAllocatorDefault, &fsRef);
StringRef = CFURLCopyFileSystemPath( URLRef, kCFURLPOSIXPathStyle
);

CFStringGetCString( StringRef, (char*)&theFile->FileName,
sizeof(theFile->FileName), kCFStringEncodingMacHFS );

But I got full file name, is the way get only filename? Of course I
can parse it for "//".

Mach thanks!
