Local files suddenly gone to online only?!

[Dave4443]

I was downloading a bunch of files with selective sync, it had done 90% of them, and then said it struggled with the last video, I hit retry, came back after an hour and instead of finding them all downloaded (the 90% had the green tick to show me they were on my system) they decided to revert back to online only?

Why would this have happened, so I can make sure this doesn't happen again.

Hello @Dave4443, let's see what we can do here. 

Generally, when you sync items from your selective sync settings, they will automatically be set to online-only. 

Could you right-click on the folders you want to have available locally and Smart Sync them as local?

Let me know how it goes, thanks!
