TIF File on myUSCIS

Hi,

Apologies for the unnecessary question. Are the TIF Files under the documents tab on USCIS accounts the one scanned by USCIS officer about my case? Even the immigration forms weren't all scanned...just names of my parents.

I just wonder because I only see few documents out of the once in my package. Almost none of the evidence of marriage was scanned. It wasn't like just photos but we have bank statements, insurance info, rent leases, affidavits and a document showing our joint online accounts. I also supplied my college payment information with her as a authorized payer.
