Is there a way to delete saved data?

[S2]

I played the game several years ago, and I want to reset everything and start over, but I can't create two copies of save data.
So the only option is to reset the data, but I don't know how to do that.

Go to Documents, then KOEITECMO, Warriors Orochi 4, Save Data, then delete SAVEDATAU
