Problem with subfolders on CF-card

I'm very new to cam2pc but like it very much.
I'm using a Casio QV-3500EX which stores pictures on a CF-card with the following folder structure:
X:\DCIM\
X:\DCIM\QVCAM.QVS
X:\DCIM\100_0606\
X:\DCIM\100_0606\100_0606.QVS
X:\DCIM\100_0606\0606xxxx.JPG
...
X:\DCIM\100_0606\PREVIEW\
X:\DCIM\100_0606\PREVIEW\0606xxxx.JPG
...
X:\SCENE\
X:\SCENE\SCENE.QVS
When I copies pictures from my camera to cam2pc it either copies both big pictures and previews into one folder (flatten structure) or it creates a folder containing date and comment as configured plus the complete existing structure of the CF-card.
This means that I either have to skip all previews which is a lot of work (I can't virtually differentiate identical looking small and normal pictures at all because I don't see any path or size) when moving 200 pictures OR I have to move and kill some folders and rename others which is less work but still more than I had hoped.
My question:
Is there a way to specify folder names and/or paths (including subfolders) and suffixes which will be excluded from the copy process?
Then I could enter the PERVIEW folder and all QVS-files to be kept on the card or even better to be killed after all pictures have been moved successfully. Something like "Do you want to remove the remaining/excluded folders and files?".
