X Files shot on location at UMD's campus?

Question

This is a somewhat obscure question, but through a bit of Googling and a bit of background work, I've been unable to find an answer. I'm a UMD student, and have been trying to ascertain whether or not the shots of the University of Maryland in the X files are real, or shot somewhere in California. There are never action shots, simply lead characters walking into buildings, overhead shots of the campus, etc... It looks like the shots might be real (given that nothing too amazing happens), but as it was the early 90s, the landscaping has changed slightly (and it's a fairly standard east coast school architecture without an amazing amount of distinctive features). If this is an inappropriate question for this forum, what hints might I need to find out where the shots were done (are they typically listed in the credits, for example?).

Answer 1

The credits for locations do not list any Maryland locations. However, since there's no indications of how those locations were used, it would be difficult to identify what locations were used to represent UM, short of finding someone who actually recognizes the specific places.

Answer 2

Every single episode in the first five seasons was filmed entirely within the greater Vancouver area in British Columbia, Canada. Every single episode in the last four seasons was filmed entirely within Southern California. The only exceptions are the establishing shots of the FBI building and aerial views of DC, both from stock footage.
