I'm trying to organize my D&D files on my computer. I've got a folder for non-campaign specific books (Core, Complete, etc)and a folder for Eberron. But then I came to Faerun and Forgotten Realms. As I understand it, Faerun is part of Forgotten Realms, but when I look at various lists of books, they seem to be seperated in two lists. One that lists only Faerun books, and one that includes them amoung FR books. So now I'm wondering if I should make 2 seperate folders, but them all in one folder, make Faerun a subfolder under FR, or what. Any suggestions?
