Just a quick query, am I right in thinking the for CHD's CMPro won't pick up on additional CHD's in that folder if they are not needed? or am I doing something wrong?

For example for one CHD, I had the correct CHD in the folder and then put in a CHD from a totally different game and it wasn't picked up as not needed like .zip files are for roms.

There is a reason for this by the way, as I think some of my CHD folders may have extra CHD in them that are not needed!!!

Thanks
