I'll have a play, maybe find a sollution for us all to utilise. Or has someone else already done this, do tell us more.
AFAIK no one has made a CMPro dat that utilises folders. I'm fairly sure CMPro does not like folders so I doubt it can be done. Another method might be needed if you want folders.
EDIT - Sorry just tried using list tool (which I use for the dats) and even if you scan a set of folders CMPro will rebuild them into zips not separate folders. I would suggest if you want layouts in separate folders that you use Winrar to extract them all into separate folders (can be done all in one go) and then do the same for the roms. Unfortunately you would have to put all the roms into layout folders by hand, this would be a true arse ache as a great deal of the roms in the dat are not emulated so are technically unneeded to play the games.
