for future reference, it's easy to find what files get changed when, if you want to use terminal.
Open a term window and use touch to make a new file, call it x. doesn't matter.
wait a few sec, then do whatever you do that is going to change a file somewhere in your home.
Then in terminal, use "find -cm x ~" to find every file in your home that was created or modified after the file you just created.
Very useful for finding files that apps try to hide. Also finds hidden files.
