Storing Files in iCloud only
To ensure I maximize disk space on my Mac Book, I want to hold documents in the cloud rather than on the hard drive, i know that if use iCloud drive then this will mean the documents are held twice, once in the cloud and once on the Mac.
What is the best solution, I do not really want to think about using Dropbox etc, just iCloud if possible.
MacBook Air, OS X Yosemite (10.10.3)
