On my PC, the iOS apps synchronized by iTunes take up a pretty substantial percentage of my total disk space.
Since most, if not all of them, can be recovered from the App Store, is it safe to delete them on my PC?
I've already verified that removing apps does not affect any apps currently installed on my device; now I'm wondering if it might cause problems once I have to restore from a backup.
It seems as if the backup itself only contains the data of the applications, and not the apps themselves. What happens when restoring a device with most or all .ipa files missing in the iTunes folder; will the missing apps be downloaded from the app store, or will restoring the apps and their data fail?
