I don’t think these “ghost system files” you speak of are the issue. If I make the loads using mp3 files they go smoothly and much more quickly than comparable loads of aac files and are completely “choke free”. With MP3 only files in the load, the player refresh step plows through the files steadily and can even digest thousands of files on my card without abending. In short it works as it should if you limit the input to mp3 files only.
Add aac files to the player and refreshes crawl along at a snails pace. The more aac files you include the slower it loads. Add the aac files to the card and attempt to load the card contents and you are toast as the load will fail within minutes every time.
I have my proof through extensive testing trying to get this player and SanDisk 32GB card to actually work as advertised. Extensive testing is something SanDisk apparently chose to skimp on when they built this player and advertised that it would handle both MP3 and non-DRM aac files.
