ok so basically i reinstalled tiger on my macbook and i transfered my data and my itunes library had no apps because i did a clean wipe so i figured i would have to reinstall them again. however, when i dl an app that i had dl from before i reinstalled tiger, it said "you have already dl this app, would you like to dl again for free?" (free apps). so of course i was puzzled and evidently this shows that the apps are somewhere in my computer. i really want to save time by finding my apps instead of trying to remember what i had and some of them were apps that i had bought (or were previously free and are now being charged). i don't really want to buy those apps again and i was wondering where i can find these apps and how can i put these in my itunes? i cant find them in my library. thanks
