It’s a little confusing at first.

• You can drag/drop a file in the purple area: the root of your vault.
• You can drag/drop a file in the blue area: into a folder.
• You can’t drag/drop a file in the red area: a (+) shows up (using Windows anyway), and looks like it will work but won’t do anything.
