Folder View and Sorting

In the Folder view, folders are displayed in the order they were saved to the MECHEN M30 (earliest saved at the top, latest at the bottom).

To sort folders alphabetically, it is recommended to use the FATSorter tool. You can find tutorials and download links for this tool on the MECHEN website or YouTube channel.

Music File Sorting Rules:

Music files are sorted by ASCII code rules. This means Chinese/Japanese names are displayed first, followed by numbers (0-9), then uppercase letters, and finally lowercase letters (A-Z). If you require a specific playback order, you will need to rename your track titles accordingly. The third-party tool Kid3 is recommended for editing track titles and metadata.
