Yes with as many files as I have not using folder mode would be rather difficult...
I'm not sure how many devices that would have a problem with large numbers. The Opus worked just fine and iRiver Covers Story worked about 5 minutes at boot and then no problems. The devices that can use folders should be able to handle it. I can understand if the other ones struggle a bit with it.
Still I have managed to find a workaround that reduces boot time from infinity to 12 minutes.
I have posted that in the thread about boot time.
