Koland,
Thanks for your comment. I had ripped and synced four audiobook disks onto the Kindle. When I could not play them, I realized that my first hurdle was to download a .wav to .mp3 converter program to my computer and convert all the 30+ tracks to mp3. Done.
Then, I noticed that, as you said, they were playing in random sequence. Doh! What's up with that? The shuffle concept may work okay with music, but this wasn't going to make it with my book. I never would have thought to put the files into the Audible folder until I read your comment.
That done, I unplugged the USB cord to look at the results. Next problem: It sorted all the tracks from four disks together. Thus I had four 01 files followed by four 02 files, etc. It did not recognize that I had four separate folders (one for each disk) in the Audible folder. It just took all the files out of all four folders and sorted them by title...which in this case was the track number.
Next step: I manually renumbered disks 2, 3, & 4 so that for example, track number 01 on disk two was now titled 07 (following the last track, 06, on the first disk). In all, I now had renumbered all 30+ tracks so that they would sort in the proper sequence.
After all is said and done, I know that audiobooks can be played on my K2. However I will probably not do them this way. I will continue to download my books in Overdrive from the library and play them on my MP3 player. This whole process was just WAY to time and labor intensive.
