Merging .scriv files?

Hi. Is it possible to merge to separate scrivener files? (.scriv)

note: not to merge/split pages within a scriv, but to join separate files? If so, how is the best way to achieve this?

Context:
I have a large file with lots of images which was slowing down my computer, so in an attempt to speed things up, I split my scriv file over 4 files. I now need to pull them all back together into one file, and would like to know the best way to do it.

Thanks - Mark

Mark - Pretty sure you can just open separate instances of Scriv and drag files from one to the other.

You can also use File/Import/Scrivener Project… to import one project’s content into another.
