If they're supposed to be binary-identical data (same file checksums), you can use BiglyBTs Swarm Merging feature - without manually copying (which isn't as reliable due to the start/end of the files not bordering on the chunk boundaries.
If they've been modified in any way though, this won't work. However, you might be able to use its Swarm Discovery to find other torrents with the same data and complete with Swarm Merging.
If the completed files have an identical checksum in both torrents, then copying the files locally in each download folders and verifying the torrents should mark the incomplete files as downloaded and propagate to other peers.
Can you share the torrents in question? I'd like to take a stab at merging them from hex dumps as explained in my other comment. Maybe develop a tool to automate it for other broken torrents.
Not same in 2 torrents, Putting one into the other and check it will only give me 0% of the results.
cuz before posting torrent, RARBG will make changes to the source files, such as filling in its site address in the video attributes, while the seed published by N1C is the source file of the publishing group, and was not modified.
