Messed up Block Libraries

[MadeByRon]

While trying to add new downloaded block libraries for v20, I inadvertently messed things up. The Modern library no longer shows up, I think it wound up in the wrong place. Where does that library, and others I want to download, actually go? Can someone show me the actual file path? Much appreciated.

Blocks should be placed in the 'Documents\wysiwyg web builder\system\blocks folder.
See also:Blocks
Blocks, Extensions, Preloaders, Dividers, Icons and Templates are no longer in the list!

Block libraries are placed in the folder
