- (unsigned long long) sizeOfFolderAtPath:(NSString *)path { NSArray *files = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:path error:nil]; NSEnumerator *enumerator = [files objectEnumerator]; NSString *fileName; unsigned long long size = 0; while (fileName = [enumerator nextObject]) { size += [[[NSFileManager defaultManager] fileAttributesAtPath:[folderPath stringByAppendingPathComponent:fileName] traverseLink:YES] fileSize]; } return size; }
