I often find myself in this position -- checking whether there are any files in an old folder not in the new location, before deleting the old folder -- and generally re-invent the wheel. Here's a 1-liner that checks (works in Julia, similar in Python, R, other langs likely):
setdiff(
readdir("./lumber/oldfiles"),
readdir("./stuff/newfiles"))

Obvs, not checking timestamp or contents.

Edit: Julia doesn't interpret "~/"
