Suggestion

In a torrent's file/folder list, I want to be able to right-click a file/folder or set of files/folders and have qBT run a data check ONLY on those files, not the entire torrent.

Use case

I am attempting to download several mostly-identical archive "tera-torrents" (near or above 1TB in size) that have a lot of identical files. I'm also combining incomplete identical files with different names using zeromerge. Both of these cases ("archive update" torrent sets and "I copied a more complete file in manually") cause updated file data to be written to common files, but qBT doesn't know anything about the new data. The only way to tell qBT about the data is a "force recheck" for the whole torrent. It would be better to be able to selectively recheck only specific files instead. Without making qBT aware of this new data, there can be a ton of unnecessary duplicate data being downloaded and written over itself.

As a sort of semi-automated extension of this request, it would also be nice if a torrent like this could be set as a "duplicated" torrent and qBT cache the last modified time for each file write, then detect if the file time changes and automatically perform a recheck on that file to become aware of any new data.

In both cases, such a recheck ignoring the pieces that qBT knows were already completed would be helpful. Adding selective rechecking ability may also be helpful in implementing one of my requests from five years ago: #13556
