positives: Disk Space Fan Pro has a nice clean interface, scans fast, and presents summary data in a logical manner.
negatives: (1) slight clipping/overlapping of font (likely due to large DPI setting)
(2) the DSFP window only fills about 1/3 of the screen and cannot be maximized.

Considering my vision ain't what it once was, a full-sized window would be a definite improvement--after all, this is a visual tool.
