DRAWING PROPERTIES

Regarding Drawing File Properties
I have hundreds of drawings in some of my projects.
I want to link the file properties of the drawings to a common textfile, or excel file, database etc, (macro) so that I can updatetitle block entries in one location and have the entire set ofdrawings update.
What is the simplest way of doing this
Thanks for any replies.SolidworksDrawings And Detailing
