Sorry for the delay in my reply, but I was unaware that the forum didn't give new notifications on the main page for forums that I had never read. After the first few days using the forum, I never bothered to look at any sub-forums that didn't have the new text next to them in the main list.
The root cause of the problem is that LDView appends _sub_part to the generated POV name of a part that is used from inside another part. However, LDView has a map from the LDraw filename to the POV name, and once an entry in the map exists, it gets used for all subsequent uses of that same part. So if you have a part that itself includes 3008.dat inside it, then the POV name for 3008.dat will be 3008_dot_dat_in_part if that part is in your file prior to a direct reference to 3008.dat. If 3008.dat comes first in the file, then you'll get 3008_dot_dat.
Having said all this, none of the parts in my library reference 3008.dat, so it seems a bit strange that you would see this for 3008.dat.
