Send Your Feedback for Smart Defrag v4 in Smart Defrag v4 Posted February 9, 2015 I miss the indication of free space/total space for each drive. This is useful as my C: drive can be 90% full, and I can see at a glance whether I should do a disk cleanup prior to running defrag, or not.. Ah! I see it now behind the blue bar on the dashboard. In which case I change my post to suggest the details are removed from over the bar which makes the figures somewhat unreadable. Alternatively, tone down the bright blue so the details are more easy to read.
