Searching APKG-files for Cards/Notes ?

Before deleting no longer needed cards, I export them as *.apkg files for archiving.

There are now quite a couple of APKG-files in my archive folder; what would be the best way to search the entire folder for specific cards/notes WITHOUT having to re-import all these apkg files?

(unexpectedly, sometimes, I might need one or two of those archived cards again; but I want to keep the size of my profile folder manageable, so learnt cards have to go)

The files need to be imported before you can access them. You can create a temporary profile to import into.
