I had a temporary ****** in which we used Dropbox so I had to set up a basic account using a temporary email I was given. Once the ****** ended, my Dropbox account was deleted. I uninstalled the Dropbox app from my PC (Windows 10) but now I still have all my files in my what used to be "This PC/Documents" folder in this mysterious "C://User/Username/Dropbox/My Laptop" folder. I can't login to my account to change any of the sync settings and I can't just delete the Dropbox folder because it says the files are in use. What on earth has happened?
