What engraving software are you using? Is the SATB setting significantly larger in scope than the 3-part setting? If not, then it sounds as if something has been done accidentally to create such a large file.
The hand-written is a scan, which is essentially the same as scanning a photograph (although you might be able to decrease the file size by selecting black-white rather tha color on the scanner/printer), while the Finale score is printed by sending font information to the printer (or to the PDF generator) and the PDF printing software simply calls on the font information to "typeset" the document.
Thanks. It may be more than today's work, since after Mass we have Vespers, the baptism of a newborn friend of the family, a visit to the relics of Mother Cabrini ..... but I'll get to that as soon as I can.
