WP ALL IMPORT

I am using WP ALL IMPORT plugin which imports but i want it to create new folder when files reach 19500 files in the folder. I contacted the WP ALL IMPORT and they sent me reply below. I want solution as advised below. How I can import images by URL in different folders once the folder reach files number of 19,500? i want to know if i can do it in settings. We don't have any built-in settings to do that, but you can write some custom code that uses our 'wp_all_import_images_uploads_dir' hook to change the folder the images go to: [login to view URL]
