Genius work. Thank you--that's quite nifty. It even recognizes that if there's no brackets (or is it counting dashes?), there's no series, and realizes that the position of the title will be different.
I hate to push, but do you know a way to address the other main issue I had? The occasional optional file type sandwiched between ROUND brackets? Like so:
Jules Verne - Journey to the Center of the Earth (html).zip
Ideally, the best result would be to drop those file types, round brackets and everything between them, from the Title. Inevitably legit titles with round brackets could be affected, I guess, but that's a small price to pay.
I won't be greedy though. You've already saved me a ton of potential headache.
