Can older submissions be moved to a folder or archived?

Can older submissions be moved to a folder or archived?The form itself is still active so I can't move it.

Unfortunately no. If you want to archived or backup your form submission data, you can download them instead. You can export all data of your forms, then archive them.

Once your data were exported and safe, you can delete submission data if your objective was to decreased your account submission usage.
