Hello Folks.....I decided to do a clean install of Big Sur from Catalina. I used this article to do it https://support.apple.com/en-us/HT201372 After the installation was complete, there were the pictured 8 new folders appearing in Documents. The size of each folder is either 0 bytes or 31 bytes. They appear to be related to iCloud, but I have no other Apple devices. Does anyone know why they are there and what I should do with them? I haven't tried to do anything with them as of yet. Thanks.
