This is interesting. The size and scope of the filing room has never really been mentioned before, besides the bits stored in other places like the part Evil!Artie burned down which held the German records. I'm guessing when a Warehouse is moved, the records are trnslated, stored in a new filing room, and the originals are put in their own section.
