Practical uses of Toad editor file (.tef)?

One more brief question - can someone explain practical uses of “Toad editor files (.tef)”? I get the feeling they could come in handy, but can’t figure out how …

Toad editor files save connect information and result sets. One use case would be to execute a TEF file once a month and append the results set. This way you now have one file containing all months results and you can open and compare if needed.
