This is on my new car stereo that I bought from Crutchfield and installed last weekend. I have no idea how the stereo interprets the order in which the files are played back. I do not know much about computers. Or flash drives, either. All I do know is I am using these small 2 GB flash drives and I put music on them from my Itunes library off of my hard drive. I had to split up the music folders and use 4 flash drives to copy all of the songs I selected from my library. One flash drive has folders of bands beginning with the letter A to F, another from F to P, and so on down to the letter Z. I copied the songs from each band or artist in my library to the flash drives in alphabetical order according to the name of each band or artist and set up folders and albums to organize the songs the way I wanted them. When I played the flash drive in the radio, it sounded great but it would play the folders in reverse alphabetical order, starting from the last band on the flash drive. For example, the flash drive for letters T through Z would begin playing ZZ Top instead of The Police. It also made the radio control buttons that I use to select folders work backwards too.
Maybe the flash drive I am using has something to do with it. Maybe it's my computer. Maybe it is my OS has a problem. I set up folders on my desk top and moved songs from my music library to each folder, set them all up in alphabetical order and then just inserted the corresponding flash drive into the USB port on my computer and dragged the music folder to the flash drive. When the computer copied the songs from the folder to the flash drive, it did it in reverse order. The T through Z folder started copying ZZ Top first, then it was all copied backwards to the flash drive.
I am using a brand new Pioneer car radio that has a USB port on the front of it:

Maybe it is just my ignorance about computer gear but I can't see how a major quality brand like Pioneer would design a radio that reads files in reverse order on purpose. I am using these little flash drives that I got from Walmart:

I use this type of flash drive because it is small, has a low profile, does not get in the way of any of the radio buttons and does not stick out like a sore thumb on my dashboard. I know I could buy other flash drives with more storage space but I use the little Scosche drive mostly for aesthetic reasons. I have 1,750 songs stored between the 4 flash drives, they work fine and sound great. I played a song from my flash drive, then I played the same song from my Ipod and I honestly could not tell any difference in sound quality. I also like not having to fiddle around with my Ipod in my truck.
That little tool I found online put all my flash drives in the correct alphabetical order. It was quick and easy and it did not cause any problems with the flash drive or my computer. My stereo plays the files back in the correct alphabetical order too. Maybe I am wrong but IMHO this problem has to be due to some error in the way my computer copied the files.
