Is there a way to save as Psd files into PNG files in bulk?

Hi everyone.

I am trying to make a massive save as from several folders that contain psd files.

Visiting the Image processor I have noticed that only files as jpg or tiff can be created.

I was wondering if there's a script that lets me choose the psd files folder and save each of contents in PNG files with same name and with "Larga file size" option checked.

An extra for thisscript would be to choose the output file size before executing the Saveas

Thank you so much.

Regards
