Local Storage Full and Cannot Upload to iCloud
I have a MacBook Pro using Big Sur 11.2.3 with 250 GB of local storage . I upgraded to the 2T of iCloud storage as part of the my Apple One subscription. I'm attempting to upload about 750 gigs of files from my external drive to my iCloud by moving them to the iCloud Drive in my finder, however when I do I get an error stating I don't have enough space on my local drive to do this. I also attempted to move the files to my iCloud Drive using the iCloud website, but copying entire folders isn't supported.
What is the best method to transfer the 750 gigs of files to my iCloud Drive? Also is there a way to do this without filling up my entire local drive?
Thanks.
MacBook Pro
