Music Sorting and Playlists

Sorting Music Files

To ensure correct playback order, sort music files by name (ASCII) on your computer before copying them into the player. Use applications like "Advanced Renamer" (available at https://www.advancedrenamer.com) for batch renaming and sorting.

Using Advanced Renamer:

• Choose "Add" > "Add files" or "Directories" to add your music into the list.
• If there are existing methods in the list, click the "Clear" Methods toolbar button.
• Click "Add Method".

Sorting Audiobooks:

The player arranges audiobooks in the following order: author, name of book, then sections or chapters. To keep different book titles by the same author in correct flowing order, create a separate folder for each book title. Keep all books by the same author under the author's name. The player will arrange titles of each book by the same author separately and keep the chapters in chronological order within the correct audiobook. For example: (Author Smith has two books, Happiness and Dealing with Loss) Smith > Dealing with Loss > section01, 02,.... Smith > Happiness > section 01, 02. Once you have finished listening to "Dealing with Loss", the player will start playing the next book, "Happiness".
