DL the file >> Go into photoshop, look for 'load brushes' Check where your photoshop loads them from mines from AppData/Roaming rather than Program Files(x86)grrr for having to look more!
Then, as this is .abr already, drag and drop the file into the brushes folder(under presets in the photoshop folder) Then re-open photoshop and taadaa, it should come up as a little folder in your brushes
I'm sorry, but I don't get it.... Would you mind explaining to me what this "brushes","wub", etc. is? You don't have to answer, but it would delight me so for you to. I am very sorry for the inconvenience.
