For those not familiar with Steve Stafford he is definitely one of the Revit rock stars and he has a very informative Blog called Revit OpEd which I am sure most of you are aware of.
One of Steve's recent postings was on "Local Files - How, How Often and Where?" is a really good document worth adding to your personal or firms documentation.
The firm I work for follows are very similar process that Steve outlines though we have a few twists on his guidelines.
I also recommend bookmarking Steve's Blog, he provides some really good information.
