Brushes disappeared overnight (are they recoverable?)
I normally use Photoshop with Kyle's megapack brush set, but when I opened up my computer today, all the brushes were gone except for the default folders. This has happened to me once before (about a year back or so), difference being that this time around I had reorganized the megapack into more accessible folders.
I'm wondering if there's any chance of recovering the brushes - I know that I'm supposed to save them to the brush presets folder (which they are currently not in) - because for some reason I'm still able to use the lost brushes in my brush history (circled in red):

Does this mean it's possible somehow to recover the brushes with the folders intact without having to reimport them?
(also, why is this happening to begin with anyways?)
