Note

In the Windows Store version of paint.net, the directories for plugins and Shapes are different. These locations need to be created manually.

First navigate to your Documents folder (this may be translated to your system language). In it, create a new folder called paint.net App Files
Then create three subfolders in the new folder. These should be called: Effects, FileTypes and Shapes.
The correct spelling of these folder names is essential, however Windows and paint.net will ignore the capitalization (or lack of).

Then i put the plugins in "Effects" right? im new to this
