If you copy the brush file to the folder C: \ Program Files \ Adobe \ Adobe Photoshop 2022 \ Presets \ Brushes, you can use it again, as shown in the figure:
The corresponding brush group name will appear in the menu of the Brush tab of Photoshop, but the brush is not directly enabled.
And restore (add) the brushes in the option group to the preset list, or import the brushes directly.
Brushes are enabled in the list.
If you close ps without deleting the enabled brushes, the enabled brushes will be written to the Brushes.psp file in the folder C: \ Users \ Xu Can \ Appdata \ Roaming \ Adobe \ Adobe Photoshop 2022 \ Adobe Photoshop 2022 Settings. In other words, with the increase of enabled brushes, the size of the file Brushes.psp will continue to increase.
Deleting the corresponding brushes in the folder C: \ Program Files \ Adobe \ Adobe Photoshop 2022 \ Presets \ Brushes will only delete the menu in the brushes tab, and the enabled brushes will not be affected; When the corresponding group is deleted from the enabled brushes, the file Brushes.psp will be reduced accordingly.
Ps: If all the Brushes are imported into the Brushes folder, it is recommended to restore which group of brushes to use, and delete them from the enabled list when not in use, so as to avoid occupying the space of disk C repeatedly (the files in the Brushes folder increase and the file size of Brushes.psp increases); Or directly load brush into the enabled list (only increase the file size of Brushes.psp) to avoid taking up the space of drive C repeatedly.
