Obviously, he should have handled it differently, but think about it.
He could have easily blamed the lack of a client list and records on the swamp-nest FBI and the Democrats. Why didn't he?
Bondi and Patel could have easily blamed their predecessors. Instead, they were mealy-mouthed about the whole affair and kept flip-flopping. They were about to release them but then something happened. And this transpired several times.
Perhaps Trump is using the files as leverage to get other things done?
I don't know if Trump is, but someone still is. If he were using it as leverage properly, he would have demonstrated it by imprisoning someone. You have to use the sword to make people afraid of you using it. I think some of the swamp creatures around him are covering it up and protecting their own ass.
