推荐答案

如果您的意思是SD卡(安全数字闪存卡)，文件系统与其他任何文件系统都没有区别(嗯，这仅取决于您格式化的方式).顺便说一下，您是否曾经在系统中格式化过卡?您也可以在设备(如数码相机)中对其进行格式化.

If you mean SD card (Secure Digital flash memory card), the file systems are not different from any other (well, it just depends on how you format it). Did you ever format the card in your system, by the way? You can also format it in your device like digital camera.
