How extract apps from a iTunes backup file?

I have recently restored my iPhone using the IPSW file but before this, I had made a full backup of my iPhone using iTunes.

Now when I restore the backup, it just brings icons of my app and needs to be downloaded and besides that, I had many files inside one of my file explorer apps(in my case it was 'offline' downloader and file explorer).

My question is how can I retrieve those files and apps? is it possible?

My OS is windows 10 and my Itunes is Version 12.10.3.1

Solution 1:

iTunes hasn't saved or restored ipa files in a long time. Apple expect you to recover everything OTA [over the air] these days & assume you have a current online backup over iCloud.

This function change arrived with version 12.7 - http://osxdaily.com/2017/09/13/itunes-12-7-update-removes-app-store/

If you do already have an ipa of an app no longer available from the App Store, you can use Apple Configurator 2 to restore it to the phone. There are other MDM solutions that allow tethered app installation as well if you really need that capability.
