You are running out of file storage

Every plan includes storage and higher plans include more. You can see what is being used, clear out what you no longer need, and buy extra space if the photos add up. Only files shared in a workspace are ever offered for clean-up — attachments on invoices and estimates, along with your logo and profile images, are protected whatever state the document is in. Nothing goes straight away either: cleared files sit in a recycle bin and can be restored.
