Fireworks batch process folders?

I have approximately 100 folders, each containing approximately 10 images. I want to batch process all of these images to be resized to within certain constraints. I would like to process all images at once and have the resulting images saved to folders they originated from. Is this possible?

So far I can select files **within **a folder, but I can’t select folders themselves, which means I have to go through every folder manually.
