Hey! I’ve run into this too - it feels like the database overhead can really crawl when you’re just trying to pick out a few specific items from a massive backup set. One thing that helped me was optimizing the local database, but if you’re just trying to parse a huge list of paths or filenames to see what’s actually there, sometimes it’s faster to export the list to text.
If you end up with a messy list of file paths and need to clean out the duplicates quickly to see what you’re working with, I’ve been using this list cleanup tool lately. It’s way faster than waiting for the UI to refresh when you just need a clean list of unique items to cross-reference.
