A fairly simple script to list all directories and files in a base directory. Then allows users to navigate through the directories and sub-directories.

You can find more scripts on my site here

Featuring a fairly simple permission mode, you can set if the user can navigate above a given directory. You can also disable the whole script by changing $allow_access to 0.

Note: Requires 2 images of your choice (A directory image and file image)
