I have 7 save game folders. I play a lot of themed games: stone age, medieval, Victorian, modern, etc. I put each one in a separate folder so that I only have downloads for that particular theme to keep from getting such a huge downloads folder. But each of those seven folders has all six Maxis hoods. If I delete some of those hoods will the game replace them the next time I start up the game with that folder? (I do occasionally play all the Maxis hoods also but not in every folder.)

Does anyone have any other suggestions for ways to organize?

Go into your game folder in the "My Documents" folder where you play it from and where your downloads are saved (in 'The sims 2' folder); and delete the maxis' hoods.
Just keep the saved themed hood that you want.
Not, the game won't automatically re-load the other hoods.
That just happens when generating a brand new "The Sims 2" folder.
Hope that helps.
Your themed hoods sound interesting !! :D

@Tleilaxu3 - Thanks for the reply. Have another question. Can you transfer a hood folder from one game folder to another? I found a folder of backed up games that were transferred from an older computer. Some of those hoods no longer exist in any of my game folders. I have previously only replaced a corrupted game with one of it's backups. But I thought the NeighborhoodManager might not be able to handle a hood number that had never been created in that folder.

yes, you can. Be sure there is no hood in there with the same number and delete the manager file before load up. It regenerates and takes on the new hood.

What joeandsarah said.... thanks !

Thank you so much!! That is a lot easier than what I was thinking I might have to do.
