If it is your intention to file a motion to quash, that needs to be done and decided BEFORE the scheduled deposition.
So, you may want to contact the attorney who issued to subpoena
and ask them if they will adjourn your deposition so that you can have your motion filed and heard.
If the attorney will not grant the request, then you have to file two emergency motions (1) to adjourn the deposition, and (2) to quash the subpoena of the requested documents/materials.
If a court does not issue an order quashing the subpoena, then the requested materials must be produced/when directed. Otherwise, you can be held in contempt of court for not honoring the subpoena.
