I have three folders which are showing a small red exclamation mark in the menu bar on the left side of my file explorer.
For two of these files I've just ended a collaboration. For the third I have deleted the entire folder and all contents.
The exclamation marks did not show up immediately, but a day or two after deletion/ending collaboration. There is nothing in any of these folders. They will not go away when I try to delete them. They are also not visible or available when I open box on my desktop (chrome). How do I get rid of these files in file explorer?
Thank you.
