It does. File Station gives you a full file browser where you can move/delete/rename as appropriate.
What you need to do will vary slightly depending on how you’ve set up the container, but you probably just want to stop the container from within Container Manager, delete the contents of whichever folders you’ve mapped as /config and /cache in the container, and restart the container.
