Can't Copy File [to iCloud] not enough free space
I have a large iPhotos library, over 200GB from past non-flash iMACs, got a new iMac that couldn't handle my storage requirements [WTF] so I had to store it on external hard drive. I want to copy that library to my iCloud account in case of HD failure/local issue but I can't copy the file to iCloud, get not enough free space errors. I have 2TB on iCloud with less than 200GB used, so thats not the space issue. I have 50GB local free space on iMAC drive. Please tell me its not trying to do something here with my iMAC drive, storage wise like caching the file locally, to move this file as it couldn't fit on the **** new iMAC to begin with.
iMac 21.5″, macOS 10.13
