Can I seed on torrents I have not downloaded but have the files to?
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:
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?
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?
If you find a torrent with the exact same files, yes you can seed without downloading first.
What I do it's to start the new torrent so it create the files. Pause the torrent. Overwrite the created files with the files I already have. Then verify the torrent. And finally resume it to seed.
From my experience if you already have the files there it will just start seeding right away automatically once it confirms the files are already present. I guess it varies from client to client.
Not as far as I know, but you should be able to find it based on the folder or file name relatively easily. Btdig.com might be of help here.
Correct, assuming the files match. I’ve done it a number of times when setting up Transmission on a new device while I still had my files and the .torrent files or magnet links for them.
You can try creating a torrent with the file(s) you have at hand and try to search with the info hash. You need to be sure the metadata (e.g. name, size, directory stucture, etc.) of the file(s) in question is identical to the original download.
You can try adding the torrent into a client. Pause it and then copy the file(s) to the download destination. Rename the file(s) accordingly. Ask your client to recheck/rehash the file(s). If the file(s) is/are identical, it will work.

Yes and no. You may have some luck using a torrent search site with DHT crawler to see if it managed to index the torrent hash you are looking for. e.g. BTDigg, Bitsearch, etc.
But that's only one piece of the puzzle, if the torrent swarm is dead (no seeds/peers) then the torrent hash alone is not very useful. You require a .torrent file to reseed dead torrents. So without a .torrent file you'd better hope the torrent you are looking for still has some peers on it.
Bitsearch is definitely your best friend here. It seems like it has the most complete collection overall.
If the torrent is dead dead, the infohash isn't entirely useless, because you can use it on torrent caching sites to try and retrieve the .torrent file. The main ones that come to mind for me are itorrents.org, torrage.info, and btcache.me.
It depends on your client, but yes, it can be possible to recreate a folder/file/naming structure with the exact same files, load the torrent without starting it, force recheck, and then you may have some metadata type files to wait to download before seeding, but you'd be helping the network a lot.
Edit, but you need to find a torrent that has the exact same files even if it's not the one you originally downloaded from.
I would recommend considering Fopnu, Soulseek, ed2k, and DC++ as alternatives for sharing. It's only opening the program, choosing the folders to seed and that's it.
I haven't been able to share much on torrent because I run into memory issues but on those programs I've been able to share a lot, specially in nicotine+ I've been able to share all 160 TB with it being as lightweight as ever. And of course I feel safer sharing without a VPN on there since I've never heard anyone complain about legal issues.
