While transferring my purchased files from my iPod to my iTunes library I noticed that a large amount of my purchases were deleted during the process. I have records for all the purchases that were deleted. What do I do?
just re-download them and you wont be charged as you have already paid once for those apps
any paid apps that were bought earlier, if you download them again no charges incur
To redownload them see:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
Retrieving data ...
