I have ben trying to find a good way to get an accurate count of files on a Volume. Using a NSDirectoryEnumerator takes way too long (a couples minutes), so, I figured out how to do it on the old Carbon FileManager using [FSGetVolumeInfo...]

Is there a better way of doing it? Maybe with Cocoa tools?

If you want a non-Carbon way of doing this, take a look at statfs64(). It's not technically Cocoa, but it's not Carbon and it works just fine.


An equivalent to your code would simply be:

#include <sys/param.h>
#include <sys/mount.h>

// ...

struct statfs64 fsbuf;
if(!statfs([volumePath fileSystemRepresentation], &fsbuf)) {
  self.count = [NSNumber numberWithUnsignedLongLong:fsbuf.f_files];
} else {
  // handle an error...
}


PS: Any reason why you're using a NSNumber as the property? It'll be a lot easier to just use an integral type unless there's some pressing need for an object.
