Which dont not come near to the original figure. Are we just looking in the wrong place? Is there any other way to check the total volume of file storage used per base?
Yes, the “Base Status” only displays the size of the actual base data without considering assets.
It is essentially the output of this API call: Get Base Size
There’s the /api/v2.1/dtable-asset/$UUID/asset-size/ API endpoint (which is currently not documented on api.seatable.com) to get the total size of all assets of a single base (accessible through an account token).
However, I don’t think that this is exposed anywhere in the UI
