I'm running the Adobe Creative Cloud with file syncing. They graciously hand out 20GB of cloud storage that works like a dropbox file. I find it very handy as I sometimes work on my laptop and other times in my office on my iMac.
Anyway, clicking on the gear wheel shows that I've used 80% of my 20GB. However, when I open the folder and check the INFO for each fold, I'm only using about 10GB. I've emptied the trash folder but still no change in the %.
