In Gizmos (2nd ed.), if someone performs the "research action" and files a gizmo, does that count as a "file action"?
Yes


  RESEARCHChoose any facedown Level Deck (1, 2, or 3) and draw a
  number of cards equal to your Research Amount. You may not
  draw from more than 1 Level Deck at a time. Each player starts the
  game with a Research Amount of 3, but some Upgrade Gizmos
  may increase that number.
  If there are fewer cards in the chosen Level Deck than your Research Amount,
  draw only the number of cards available.
  After you draw the cards, choose 1 of them and either Build it (if you have
  enough Energy) or File it (if you have space in your Archive). Or, you can choose to
  do neither.
  Return the remaining cards facedown to the bottom of the corresponding
  Level Deck, in the order of your choosing. You may return all drawn cards to the
  bottom if you wish, or if you can’t File or Build any of them.
  Note: The File or Build Action you perform during a Research Action also
  counts to trigger active Gizmos (see Triggering Gizmo Effects below).[bolding added]
