Stop Itunes From Storing Apps on Windows

Question

I was wondering if we're able to disable iTunes from downloading and backing-up Apps onto my computer (windows). It's taking a chunky load of storage (10  GB), and would prefer just downloading directly off Apple store if needed.

Answer 1

That doesn't appear to be an option. You can however move the backups off the system drive if that helps.
Relocate iOS device backups
Make a new folder called MobileSync at the root of the drive you want the backup data to live on, e.g. as D:\MobileSync
Use Windows Explorer to move current Backup folder at <SystemDrive>\Users\<User>\AppData\Roaming\Apple Computer\MobileSync\Backup into the folder you just made. If the backup folder is large this may take some time.
To make iTunes look for the data in the new location copy the text below, open a command prompt, right-click to paste in the command, edit the drive letter/path if needed, and then press <Enter>.
MkLink /J "%AppData%\Apple Computer\MobileSync\Backup" "D:\MobileSync\Backup"
If you want the backup elsewhere replace D:\MobileSync accordingly.
Note that while this method works for iOS device backups it cannot be used to redirect sections of the media library.
If you're considering relocating your media folder see Make a split library portable for background.
