This arises as a matter of (1) housekeeping and (2) curiosity.
I have a far amount of (now ancient) DEM data in the TF directory designated for that under options/preferences.
Is that merely a legacy setting at this point?
Or is that data more detailed than that which is now downloaded concurrently with map data?
Despite my packrat tendencies with data and the tedium I recall going through to acquire it, I could just as easily benefit from cleaning up my TF/GPS installation.

Thanks.
