This script can be placed in a folder and will display the contents of the folder based on the file extensions you define in the settings below.

With this function you can:
- define a specific list of extensions to display on the page
- define a H1/title tag for the page
- define a custom logo
- restrict search engines from indexing the page (noindex)
- sort the list by filename ASC or DESC
