I would like to be able to just clear certain folders without clearing everything. For instance. I would love to be able to keep a library of Darks/Bias/Dark Flats, etc in their own respective folders on the USB drive, and then, when it comes to deleting old Lights, I wouldn't lose these valuable and repeat use files.
The AIR has improved my enjoyment of this hobby by leaps and bounds! I hope you can continue to improve it!
