No worries, I assumed it was just a typo on your end and you meant to put 64 but had 128 in mind. But even at 22.6meg per file, I know I have a 60 file collection of classical music that's roughly 18 gigs. I wish I had done a better job with labeling them however, because its a real pain to find the particular cd I'm after sometimes.
Yeah, I've had similar issues. But my point still stands, I think. If you've bought a FiiO to listen to over 5800 files, a fair percentage of them must be lower than ogg at Q10, so...why exactly are you using a player that has as its main differentiating feature (and main reason for its price tag), the ability to play high res files? Certainly not the form factor, battery life, strange UI, occasional lack of stability...etc.
No offense intended to anyone, but it just has me puzzled.
