No one seems to say much about this. This is my second Pioneer unit that I have done it to. Buy an external hard drive and reformat it FAT32 and throw on a bunch of music. My 5000UB had a limit on the number of folders and files. That is fine. Anyways, before I bought my F700BT I made sure to see what the capacity was on folder and file capacity. In Pioneer's manual I swear it said unlimited. However, I found on a few sites it said only 99 folders and 999 files. I would sure be angry if Pioneer was wrong. Anybody able to confirm the max capacity on reading an external hard drive. Thanks,
