Our company is currently on the Business Plan, and as such are limited to 1TB file storage. BTW - We're keen to remain on Business, and not upgrade to Enterprise.
We're coming close to the storage limit but have no way of identifying which sheets have large file attachments. And thus, the ability to potentially purge the sheets in question, or remove the attachments from those sheets on mass.
Idea request: Add an "Attachment Size" column in the Sheet Access spreadsheet action available under the User Management section of the Admin Center.
