- (void)removeFileWithName:(NSString *)fileName{    // you need to write a function to get to that directory    NSString *filePath = [[self stringForDocumentDirectroy]stringByAppendingPathComponent:fileName];    NSFileManager *fileManager = [NSFileManager defaultManager];    if ([fileManager fileExistsAtPath:filePath])    {        NSError *error;        if (![fileManager removeItemAtPath:filePath error:&error])        {            NSLog(@"Error removing file: %@", error);        }        else        {            NSLog(@"successed removed file");        }    }}
