Does anyone know, perhaps from past experience with TWD1 > TWD2 imports, if I need to keep either or both of the first games installed in order to import my save game?

When I imported into TWD2, I think it looked in a specific folder for the file, and I don't think that folder would have been there had I already installed TWD1, which I hadn't.

I'm trying to clear up some space on my HDD and I want to uninstall them, but I want to make sure that simply backing up the save files is enough, or if I need to leave the directory structure intact.

Thanks!
