Maybe you have to try two modules who allow to manage files in Drupal:
The Media module provides an extensible framework for managing files and multimedia assets, regardless of whether they are hosted on your own site or a 3rd party site
- workbench media : it's an integration of the first module in the workbench suite, that's great if you want a listing of all your files uploaded in your site.
If you just want to display files to the users, you can do that quickly with views:
- Add a new view
- In
showsection select files
After you'll be able to show all the files you have in your folder (but you can also restrict to only show files from a specific content type) I took a photo of all the fields available :
