We already know that trump is probably guilty, but there is also a possibility that he is just very incompetent and innocent. It is called plausible deniability. The files that the government has would just be more of that. There is no way for the files to clear him. They might be able to clear him of one limited time child rape, but it is impossible to prove anyone innocent of all child rap yeah es, both known and unknown, for 50+ years.
The files that would be more interesting are the files trump personally has. his employment and immigration records for the children he procured for Epstein. his financial transactions with Epstein. The guest lists for the girls at his calendar parties.
All these records have never been in the custody of the government, but rather in the custody of trump personally. I would bet trump has already destroyed those records, partly when he decided to drain the pool into his server room.
