The Davalos-Carron's Law seems to be holding.

The Davalos-Carron's Law states that the size of the text in all of one's Email stack is exactly a thousands times less than the size of the all its related file attachments (jpg, mpg, pdf,......) We currently have in our collaborative project system something like 12 MB of text for the different "E-mail" exchanges we have with each other (threads), but the size of the library associated with this application which hold all the attachments associated with these threads is now 12 GB.
