necessities to backup brushes tutorial
I strongly suggest you backup your brushes so if your PS ever resets and deletes them, you'll have a backup and can easily restore them. Nobody wants to redefine all of their brushes. That's a pain in the ass.The Steps
1. Click on the brushes drop down arrow. Click on the side arrow outlined in red.
2. Click "Preset Manager." Hold in CTRL and then press the A key on your keyboard. If you did this right, it should have selected every brush you have in your brushes section. Here is a small little section of mine just so you see what I mean.
3. Click "Save Set..." Make sure you save them in a folder that you will remember later!
