This is one of those handy little apps that Apple should add as a Finder option in OS X. It provides the same functionality that Mail has for its trash folder--a timed delete. TrashCache has already saved me a few times since I've been using it. It's small and unobtrusive. You don't even know it's there. But when you need it, you're glad it is there. :-) I can't say enough good things about it. It just works!
