What is a free and preferably open-source way to automatically move files from one folder to another on android?

My case: Basically my Camera app doesn’t allow for me to set where to store the captured photos, so I have to move them each time. How can I automate this?

I want to make all files that appear in one folder, (/DCIM/Photography_Pro/) moved to (/DCIM/Camera/).
