Hazel
Hazel watches whatever folders you tell it to, automatically organizing your files according to the rules you create.
Spend five minutes with Hazel, and you’ll never have to tidy up the Desktop or Downloads folder on your Mac again. Spend ten minutes with Hazel, and you’ll be automating iPhoto imports, Trash-emptying and file labelling. Spend half an hour with the thing, and it’ll probably make you a nice cup of tea and a slice of toast.
