- This article refers to the in-universe Alien Files. For the webisode and television series, see Sarah Jane's Alien Files.
The Alien Files were a database created by Sarah Jane Smith. Realising that she and the rest of the Bannerman Road gang couldn't defend the Earth from aliens on their own forever, Sarah Jane instructed Mr Smith to begin collecting their knowledge and experiences about the aliens they dealt with in hopes it would be of use to future generations. Sarah Jane and friends began regularly recounting their adventures to Mr Smith, who collected the data and uploaded it into Alien Files about the alien individuals and species involved. (TV: SJAF 1)
