Cocoa Snippet: Finding a File’s ‘Kind’

+ (NSString *)humanReadableFileType:(NSString *)path
{
NSString *kind = nil;
NSURL *url = [NSURL fileURLWithPath:[path stringByExpandingTildeInPath]];
LSCopyKindStringForURL((CFURLRef)url, (CFStringRef *)&kind);
return kind ? [kind autorelease] : @""; // If kind happens to be an empty string, don't autorelease it
}


Thanks very much to Peter Hosey and David Phillip Oster for being unbelievably helpful in clearing up the labyrinth that is CSStringRef to NSString usage.
