@Sorensiim when you have a minute can you please warn our DX50 users on the first page or FAQ about the following:
Under 1.2.6 now the scanning algorithm creates a new directory on the SD card called .audio_data and a database name audio.db. I do not know for certain what's in that database but my instinct tells me the scanning results (most likely cover arts info - who knows?). If you loose your cover arts, I would strongly advise you to delete the directory and re-scan your SD card library or else you won't have the cover arts showing on your DX50. Once it is done, then just keep it there for the dap to figure out what needs to be added. Thanks iBasso for introducing additional artifacts on the external SD card that creates more trouble than it is worth. I would suggest you add the playlist in there, that would be more useful.
One more thing, if you now look into your .album_img directory on your internal DX50 memory, it does not contain path names any longer just some sort of fixed coded strings which most likely works with the audio.db database referred above, so now we have two locations to worry about for scanning results.
I am going to do an experiment and switch my SD card to see what happens to the other one, if it will be faster and keep the scanning results intact when switching. Nope no cigars here, scanning is done as if the card got inserted for the very first time.
