very good - but not well programmed

'm very happy with processing, operating Dung, very robust.
But I put on PC folders such as literature and if the folder is dragged to the player, this and the files are simply disappears into the large pool of music and literature pushed files and mixed. Although the then grouped by file name (should all have the same name), but that's still totally impractical because you have to look ind he long list of files afterwards !!
and if you have any files named the same on the PC eg, steps back just a number for the order and you copy the files to 2, then 2 groups of the same name created. what is that because.
But otherwise spotless, even the sound and especially the radio, which is why I have the player ever bought.
