It's been a LOOOONG time since I did this, and while I thought I remembered how, either my memory is failing me, or this version doesn't let me.
I'm using 4.17pre27 (I think, anyway it's the latest open-source version.) I have a bunch of FileTypes defined from way back, and would like to add some new ones. Anyone recall how to do this? I also cannot seem to find the original archive with the documentation. :-(
Thanks!
