How can I merge Bookmarks folders so they work together?

I have a Safari Bookmarks.html folder from an old crashed HD that I would like to merge with

my current Bookmarks.plist folder so I can access all the Bookmarks from the same open book

icon on my Menu bar.

Is that possible and if so will I be able to read all the Titles that I created in my old Safari Bookmarks.html

folder along with the new Titles I created in my current Bookmarks.plist folder?

Any help will be appreciated.
