This is a Contao-4-Bundle meant to adapt the folder structure inside the files-directory directly to the page structure. To install it, search for the project in the contao-manager since this is a Managed Edition Plugin.
For the bundle to work, you need to have a folder called "daten" in the first level of your files-folder. This is the folder all the folders for the pages will be created in.
Warning: Backup your files before using any of the functions provided by this plugin!
