This is an old revision of the document!
When you connect the music player to a PC using the provided USB cable, it is detected as an USB mass storage device, so you can copy music tracks to the internal memory. I used an organization by album, i.e. all the tracks composing an album are stored into a single directory.
When you eject the device from the PC operating system, the player updates its the music library scanning for ID3 tags. I used V2.4 tags, which are recognized correctly. If the music collection is correctly tagged with ID3 tags, the player can browse the music collection by artist or by album, in alphabetical order. This is very handy.
In the above pictures you can see how - in the Album view - the names are truncated to 12 characters. Browsing the file directories (in my case each folder is one album) the file names are truncated to 19 characters and they are not sorted.
One of the worst defects for usability of this player, is the user interface truncating ID3 tags: album name, track title, artist name, everything is truncated in player screen. This is very unpleasant, considering the fact that the display would be wide enough to show much more.
I tested the player uploading an archive of tracks organized into directories, i.e. every directory contains all the tracks from a single album and every track is named as "%n %t" (track number, title). It turned out that if a picture named folder.jpg exists into the directory (a convention used by the Kodi multimedia player), that picture is shown during tracks playback. Unfortunately that picture will hide the ID3 tags, even the filename of the playing track is replaced by the picture filename: a very silly behaviour! Other times I got chineese characters instead of the image name, mixed with part of track name; so definitely there are bugs in the management of file names, where the Vfat filesystem is a source of countless problems.
It is also unclear why the image is sometimes resized correctly to occupy the entire available space, other times it remains much smaller.
