I was under the impression that brushes will only show under preset manager if they were manually loaded into photoshop by selecting Brush then Load Brushes and then selecting the abr file you wanted. I always save my extra brushes/styles/actions etc under seperate folders away from Photoshop as you can easily direct the Load Brushes etc to where you have them saved and then load from there easily. And as I have many of these extras, keeping them seperate from Photoshop saves load up time when starting Photoshop. Hope this helps
Look at the full path. You're not looking at the folder you think you are...
Yes, this is true.
I copied the full path from Explorer into the Load dialog's File name box and that was successful.
Why is there ANOTHER path called "Adobe Photoshop CS5\Presets\Brushes" which opens **by default** and screws up so badly?
Because the defaults are installed in the application/program directory, where Microsoft doesn't want you writing.
So Photoshop has to save and default to the user directory where they should be saving files.
This is the wonder of UAC and the transition of Windows from a single-user system to a user-based system.
