Find the translation data of a Bookmark?

Hey all,

I recently had a map somehow corrupt itself to the point where my system hard locks every time I try to build lighting. Problem is I had a few bookmarks that I had created in the perspective for key camera angles that I hoped to use and when I copied all of the content into a new map file they were of course lost. Does anyone know if it’s possible to get the translation info from a bookmark so that I can re-create it in the new map or if it’s somehow possible to transfer book marks from one map to another? I don’t even know where the bookmarks are stored.
