Do you mean a file that's attached to the PDF? It's not possible to do that.

However, you can attach the file, check the size, and then remove the attachment before saving if the size doesn't match the criteria.

That won't work because the file-size value only updates when the file is saved.

True... for the PDF. But you can get the file size of the attachment immediately after attaching it.

True as well...
