Photoshop - Preview Brushes Without Loading them Into PhotoShop

Does anyone know of a way to ‘preview’ PhotoShop Brushes before/prior to loading them into the PhotoShop app itself? Or is the only way to see the Brushes is only within PhotoShop?

Related question:

  1. Most effective way to manage/organize PSD Brushes?
  2. Has anyone experience a situation where you’ve organized Brushes to your own liking in specific folders, only to go back to PhotoShop a day or so later and all that organizational work is no where to be found? Is there a setting in Photoshop that will save however you organized your Brushes?

Thanks
