The true issue with releasing the files is that once they're out there done.
Right now Trump could use them as a bludgeon on his enemies. The files represent a critical level threat to anyone whose name is on them and the only people on them will be the rich and powerful because that who Epstien hobnobbed with exclusively.
We know that Bill Clinton will be on there for sure along with probably many politicans of both sides, we have photo's of many high up kid diddlers in Hollywood on there, we know that many many rich fobs will be, all who fund or shill the progressive rot infecting the Western world. So why not use that as a club to keep them in line and get them to stop all the lefty shit they're paying for. Hell get them to pay to undo all the shit they've done.
Once the initial surge of reprisal goes out and trust me these types will have the money and the PR firms to weather it, the files will be just so much trash.
Aside from assuaging our curiosity giving out the files is a poor choice IMHO.
