For iOS 10 through 15, you will have a Manifest.db.
There's a chance it's going to be encrypted.
If it is, when you parse your backup,
you will enter the passcode to decrypt.
It will decrypt that database.
It is going to have the file ID, the domain
for the app, the relative path.
I can honestly say I have never used this forensically,
but I want you to know that it exists.
