I have a class that implements the ProjectComponent and PersistentStateComponent interfaces. It is annotated with @State and the name field is set. The state class is also nested in the class I am trying to persist.
The documentation states that these are in an .ipr file, but I don't see an .ipr file anywhere in the project directory. I did a search globally and nothing seems to come up either. Where on Windows 10 is this file?
