Folders from external hd, copied to iCloud Drive, duplicated in Mobile Documents
I have copied a number of folders from my externals HDs to iCloud Drive, and they appear duplicated in Mobile Documents in my Macintosh SSD disk, taking valuable and expensive espace. My objective is to have a backup of important stuff from my external HD to iCloud Drive.
How could I avoid these folders and files from external HDs being duplicated in Mobile Documents?
In summary, I copy folders and files from external HDs to iCloud Drive, and the iCloud copies these folders to Mobile Documents.
