If you’re like most people, you probably use Dropbox to store your files. But if you want to delete files from the service, there are a few steps you need to take. First, open the Dropbox app and sign in. Then click on the three lines in the top left corner of the main screen and select “Delete Files.” You’ll be asked to confirm deletion before deleting any files. Once all of your files have been deleted, you’ll need to sign out of Dropbox and re-enter your credentials.
