+## Mac OS File Attribute List
+
+This list contains extensions and their Type and Creator for vintage Mac OS (System 9 and below). I'm populating this list as I encounter them, so it's not a very long list. There are other resources available[1], but some of the files listed here might not be there. I use DropAttribute to change the files[2].
