A: Customers who enjoy audio book will need files sort by alphabetic order. The easiest way to do that is go to “Artist” or ”Album”. And find certain artist or album you want, all audio will be sort automatically by alphabetic order there.

If your audio files don’t have artist or album info, then you need some tricks. Because MP3 player has different format compare to PC/MAC, files won’t be sort by alphabetic order when you use “folder” or “folder view” function. Some convert software may help you solve the problem. But there’s still a easier way to do that.

Please follow these steps to sort the audio:
1, Prepare you audio book files on PC/MAC.
2, Make sure these files are in correct order by file name. Such as “01 xxx”, “02 xxx”...”50 xxx”.
3, Now plug in your mp3 player and ready to transfer.

5, Select all audio files and do not copy or cut.(Important)
6, When all files are being selected, move your mouse above the first audio file (ie “01 xxx”) and then right click and copy. (Important)
7, Paste these files to your mp3 player folder, make sure all files are pasted in right order. Otherwise delete them all and redo step 5.
8, unplug the mp3 player, and go to the folder with files, they should be in correct order.

This method is using “edit time” to sort the files, the first file you paste will be the first file be edited. Just make sure, when you’re going to copy files, sort them on you PC/Mac first, then select them all and move you mouse to the very first file to copy.
