Copying cached bake after saved new filename?


I’ve had a few times now that I bluntly save my file under a new filename, make changes, and realize that my physics that took a loooong time to bake are gone. If I copy the blendcache_filename to blendcache_newame, it won’t work. If I rename all those hashed filenames (or something) to replace a lowres quick bake, it also doesn’t catch.

Is there a way to clone my own bakes? A guy has to be able to save different versions and just copy the bake, right?
