Orange box icon meaning

I read several of the entries, trying to get rid of the file box on all my dropbox files, because it's super annoying that you can't open your files unless you're online.  I didn't see the solution, but I found one.

If the dropbox logo is in the bottom right corner near the time (Windows) right click it, then when the pop up comes up click on your initials in the top right corner, a drop down box will open and click on preferences.  A new window will pop up for dropbox preferences, click on the sync tab.  There is a section that says "save hard drive space automatically" yes or no.  I had no checked, which is what you want, but then there is a drop down selection to the right that allows you to choose "available offline" or "online-only" choose available offline.  I had online-only selected and as soon as I switched it to available offline all the little boxes went away.

There maybe another way to get to dropbox preferences, above is how I found it.
