WARNING: Error loading hardware folder C:

Hi
When I open my library manager I get a list of error messages (shown below) I think there is a problem with my HARDWARE folder. I am using IDE 1.8.7 and an Arduino Uno.

Thanks

You put a bunch of sketches into the hardware folder under your sketchbook. That tells the IDE that they contain a third party board package (for adding support for additional boards to the IDE), when they're actually sketches.

Move C:\Users\andy\Documents\Arduino\hardware\arduino_sketches-master\ folder and it's contents to C:\Users\andy\Documents\Arduino

That fixed it ! Thanks
