Of course not... this stuff are the values the plugin uses if they is no config file (or if they aren't defined there).
If you have your own resource folder, you create the config file (addonCollectionManager.ini, in the plugins directory in your profile) and add a section for each of your resource folders. But the plugin assumes (independently of built-in/config file) that your add-ons are organized with a parent directory for each type, i.e. that you have something like:
C:\Gimp
|
+--C:\Gimp\brushes
| |
| +--C:\Gimp\brushes\flowers
| |
| +--C:\Gimp\brushes\fruits
| |
| +--C:\Gimp\brushes\balloons
|
+--C:\Gimp\patterns
| |
| +--C:\Gimp\patterns\tiles
| |
| +--C:\Gimp\patterns\stone
| |
| +--C:\Gimp\patterns\wood
In which case you can use in the config file:
[brushes]
addons_stored:C:\Gimp\brushes
[patterns]
addons_stored:C:\Gimp\patterns
And the brush manager will let you activate flowers/fruits/balloons independently.
But if you keep the Gimp names for the folders ('brushes", "patterns"...) and you stuff is all kept under C:\Gimp, you can go for the simpler:
[all]
addons_stored:C:\Gimp\{type}
