Thing is, I have the batman series from the 60s that I downloaded a long time ago. I deleted the torrent but I want to seed again because I remember it having like 1 or 2 people seeding and I have better internet nowadays, I have two questions on this:

1. Is there a way to find the torrent directly from metadata on the files or some other way instead of having to search on sites until I find it?

2. If I were to find a different upload of the same files, can I just verify the files I have and start uploading directly without having to download them first?
