Unknown folders in wdisplay folder

I have noticed that I have the following folders in my wdisplay folder -

weatherdisplay (1)
weatherdisplay (1) (2)
weatherdisplay (4)

I have never noticed them before. What are they for and can they be deleted? Just updated to ver 10.37S91

Thanks,
John

those are not created by WD
maybe something to do with windows and how you unzip WD

OK, they have dates back in 2018, I just deleted them.

Thanks
