Pagesizes greater than 20 items per page

I am looking for any information on how to increase the pagesize length from the standard 20 items per page. The only thing I have found has been about modifying a file called but I am unfamiliar on doing this. I am fairly new to Plone and have not had a lot of experience with it. I am currently running 5.1.4 on Ubunutu 16.04.5. I also have somewhat limited experience with Linux.

Any help would be appreciated.

Hi Dave - do you mean when you are looking at folder_contents? or some other batching view in particular?

Hi Kim,
If I have page setup using a standard view with more than 20 PDF files listed, at the bottom of the listing it will show a dot then a 1 and then the next line will be a dot then a 2 and so on until at the bottom of this list it will say Next 20 items. The dot 1 and dot 2 and so on is the next 10, 20 items or in this case PDFs to show. I would like to be able to show maybe 50 at a time instead of only 20.
