How to automatically change the background in psd files?

I have 300+ psd files in which you want to change the background, does anyone have examples for automating things? Yes there is a built-in recording actions, but they need each file to open.

Yes there is a built-in recording actions, but they need each file to open.

To open 10-20 files at the same time and change using the action recording.
Is only 30-15 cycles, depending on the number of open files.
