How many worlds/save files do you have?

Right now I have one seeing when Stranger ville came out I removed my folder from my game as I had several long playing games in that save i wanted to put aside in hopes of Witches and University - as I had many teens I was ready to send to college in one of the saves I had been playing a long time - and another save on my Vamps kept to where i wanted them - until we got Witches added as I have another long time story going I felt needed Witches to add to the mix. So not wanting any of these games to possibly go ways I did not want them to go - I moved out the folder and started a new one with Strangerville. Which technically has 3 Strangerville stories in that folder - as I fought the mother with 3 different main sims and storylines - but eventually settled on the last one I started and have been playing in that one since.
