Re: what happens if i uninstall my sims 3 game will my family and house be deleted
yes if you uninstall with out backuping your stuff you will loose saves ,sims etc
go to the electronicsarts/thesims3 folder if you have saved sims in CAH copy that folder to the desktop will do or a flash/thumb/portable drive
copy the saved sims folder
saved games
recorded videos (if any )
screenshots (if any)
Downloads folder thas your store bought items (inculding free store items you have gotten) as you will need to install your downloads again if reinstalling the game that way you won't have to redownload your store items just open the folder and click the item to reinstall it back into your game once it's reinstalled
edit to add if you wish to save your sims and th ehouse go to edit town save them to the libiary then use the share button to export your sim/house
then in the electronicsarts/thesims3 folder copy the exports folder then when you reinstall your game you can then open the export folder click on it and install your sims/house and they will be in the libiary to place back ingame andready to play with again
