[Kindle DX] 以清單方式播放Mp3 ( Play Mp3 file in document list)

Kindle本身有支援播放Mp3的功能,如果是將Mp3放到Music的目錄內,就只能在Experimental->Play music播放,看不到Mp3的名稱也無法快轉。但如果將Mp3放到audible的的目錄中,Mp3的名稱就會出現在清單中了,方便選擇且播放的功能也比較完整。

If you put Mp3 files in music fold in Kindle, you can play Mp3 in Experimenatl/Play Music. It's not easy to play and choose mp3. If you put mp3 files in audible fold, you will find mp3 files in home list.
