ABR Viewer Software: You can use free ABR viewing software such as the ABR Viewer Brush Viewing Software, or Brushview QL ABR Viewing Software or Tumasoft's Preset Viewer. These programs allow you to view your brushes without opening Photoshop. Many Photoshop users like to keep their ABR brushes filed in a designated "Brush" folder. This makes finding and viewing the brushes easier.
