// 方法1：使用NSFileManager来实现获取文件大小
+ (long long) fileSizeAtPath1:(NSString*) filePath;
// 方法1：使用unix c函数来实现获取文件大小
+ (long long) fileSizeAtPath2:(NSString*) filePath;


// 方法1：循环调用fileSizeAtPath1
+ (long long) folderSizeAtPath1:(NSString*) folderPath;
// 方法2：循环调用fileSizeAtPath2
+ (long long) folderSizeAtPath2:(NSString*) folderPath;
// 方法2：在folderSizeAtPath2基础之上，去除文件路径相关的字符串拼接工作
+ (long long) folderSizeAtPath3:(NSString*) folderPath;
