> Thanks guys! I’ve thought about trying to split it up into groups of one or two thousand, but not sure quite how to do that. What I have tested that works is a simple message box that pops up when the user has selected more than 3,000 files and politely requests they try a smaller batch.

That’s simple and elegant. What usually works best 🙂
