Unable to Import Families in Sims 1 (Sims 25)

Hello, I purchased the Sims 25th Birthday bundle and on my computer both Sims 1 and Sims 2 load without crashing. But I was disappointed to find that many of the families that I remember (Smith, Valentino, Maximus, etc) were not there. So I am trying to import them into the game. I found the correct folder: Saved Games/Electronic Arts/The Sims 25/User Data/Import
But when I place the .FAM files in the folder the families do not show up in the game. Can someone help me with this? TIA.
