- (sizePack)foldSize:(NSString *)direString{

    sizePack sizeP;
    memset(&sizeP, 0, sizeof(sizeP));

    NSFileManager *fileManager = [NSFileManager defaultManager];

    NSArray *tempArray = [fileManager contentsOfDirectoryAtPath:direString error:nil];
    for (NSString *fileName in tempArray) {
        BOOL flag = YES;
