I have just done a small project. I created a folder. Then created a database in it, then put all the media in a folder in the base folder. So everything is self contained and I can archive the whole lot later.
When I finished the project a week later I wanted to zip up the whole lot and archive it on the NAS.
So I disconnected the database as I would close a library in FCPX.
However now I can't see any way to re-connect the database

In FCPX I have 100's of libraries one per job (which are self contained) and archive these to the NAS complete with all the used and unused media and timelines etc. Therefore the only linraries shown are the current set I am working on.
Of course at any time I can fetch the FCPX library back to the local disk and reopen it. How do I do this with databases in Resolve? I don't want a lit of 100's of databases listed in resolve 90% of which I will never open again but I never know which 10% I will need to reopen
