List contents of a directory and make links of them

Is there something that can take the contents of a directory (say, a folder of files... recursively if possible) and output a list of links with downloads?

The goal is to have a folder /assets/files/ , with subdirectories, where each document is put in a list and formatted as a link for download.

In other words this structure:

/assets/files/document1.pdf
/assets/files/anotherdocument.pdf
/assets/files/cards/somethingelse.pdf
/assets/files/cards/somethingevenelser.pdf

Would be displayed like:

Right, I did not think about this before... but Wayfinder can do something like this (I always thought about WF in terms of navigation menus).

Except it traverses the Website ’tree’, and I’d want it to list all files in a folder (on the server) instead...

I could use Wayfinder, but then I would have to create a ’page’ for each Document inside Modx... which would be awkward with the amount of documents I have (easily 500+).

The help manager hack (not needed anymore since it is included in the core) has a good example on this. It reads the files in a directory and displays them as tags in the help page. This should get you started:

The php functions you will use are opendir() and readdir():
http://www.php.net/function.opendir
http://www.php.net/readdir

At first glance this looks pretty similar. Hope this helps:
