One of the folders has an icon on what looks like a document, and there is nothing in it. The second folder is a regular envelope folder and has all the document files in it. These are displayed both on the iMac using High Sierra and MacBook Pro with Mojave. I have icloud turned on with additional documents and desks on both machines. Can I delete one of these folders and if so, which one? Do I have to move the files in the regular folder to it with the icon?
