You may want to delete a workspace if you're wrapping up a project or switching to a different workspace.
Before you do, it's worth taking a moment to move any files you want to keep to another workspace. This cannot be done once the workspace is deleted.
Make sure to cancel any paid subscription first to avoid being charged beyond your workspace deletion date.
To delete your workspace:
Head to your Workspace settings from the My files page. Make sure you've selected the workspace with the relevant subscription before making any changes.
Scroll to the bottom of the page to the Delete workspace button
