Ya, I agree...Bad feature.
Whats on this NR software designer's mind? He/She cannot possibly expect NR users to store all their scanned images onto the main drive (c) of a laptop. Especially when they refer NR to be portable. Most of us are using laptop and we need external drive to store NR data. Space on laptop is limited. I think they should refer NR as not portable so that it can only be used on my home desktop with 2TB drive.
NR Software designer....wake up!
