I think you mean "behind your back." :) I think you'll need to use a Timer here to periodically compare the actual folder contents against what's in your listbox. A period of a few seconds should be sufficient. It'll still be possible that a user could change something on disk, and then very quickly select a file in your app that doesn't exist, so you should be prepared for that case. But typically, users aren't that fast, and they'll be pleasantly surprised when they see your app notice the change, even after a second or two.
