iCloud storage is full, how to find each folder size? I'm using a 50GB plan on iCloud and now it seems to be almost full. I received the message saying it is almost full and checking iCloud discovered there is less then 1GB free.

I would like to know which are the biggest files/folders, so I can move them elsewhere. I tried to find folder size in the following way:

My-MacBook-Pro:com~apple~CloudDocs me$ du -h -d 1
184M    ./SomeFolder
1.4G    ./AnotherFolder
5.5G    ./Me
4.4M    ./.Trash
 16K    ./Downloads
7.0G    .


But, due to the mechanics of iCloud (I think) some files are stored on iCloud only, and so I'm failing to get the full size of everything.

How to proceed?
Well, you could go to System Preferences > iCloud > Manage, and see which files take the most space.
