I jumped to the end of this thread to see if anyone had solved this, so apologies if this was posted somewhere in the middle.
I too started noticing file box icons. Just within the past few days. Then I noticed that looking at any file required a wait. It was obviously downloading the files as I need them. This is not what I want. I saw the same thing happen on my dad's computer around the same time.
I was already logged into my OneDrive account.
I fixed the issue by:
- Click on cloud icon in task bar (lower right of screen). The OneDrive dialog box pops up.
- Settings gear icon.
- Settings
- Settings tab
- Files On Demand
- "Save space and download files as you use them" had somehow gotten selected (wasn't me). I unchecked this and it began downloading.
All my little green checkmarks are back. But the options to decide download status by file/folder is still gone. I used to be able to select which files I wanted always downloaded on a file/folder case basis, but that option I could not find in the "improved" Explorer menus any more. So probably it will download stuff when you open it and it will kick around for a while and then be automatically deleted.
- You can decide that anything you put in the cloud is also synced to your harddrive (steps 1-6 above)
- You can decide which folders on your hard drive drive to upload ("Choose OneDrive folders to sync" in the Explorer right-click menu "Show more options").
I have enough hard drive space so that I don't care about the new limitation.
