I know I've seen a thread like this before, but I can't find it.

Where are my custom designed ships kept, and where are the default ships kept?

I hate having to obsolete a ship every time I research a new tech. I don't want the default ship types appearing. Also, I have some custom ships that appear in my build-list, but not in the shipyard, so I can't delete them.

So, am I correct in assuming that I can wipe out all of my custom ships merely my deleting a/some file/s? Also, how much work is it to get rid of the pre-built ships? Thanks.
