There's really nothing like that built into Newsbin. Newsbin maintains a fingerprint of the first 24K of every file but it's not something you can reverse. Meaning you can't look at the fingerprint and know what was downloaded unless you also have the file on hand to compare it too. There are some features to allow the user to track the downloads but unless they turned them on (they're off by default) they're typically unused.
Downloaded.db3 is the files listing. It might contain some information like that it depends on how much you download. It's self purging. Old versions might leave the NZB's loaded through NZB Autoload in subfolders of the autoload folder but current versions move all the NZB's into the data folder where they're periodically purged after use.
