Directory Printer/Lister

I am looking for a directory printer that is open source and hopefully portable although it is not necessary. I found a really good one, Directory Lister, but unfortunately it is shareware. I've used it and really like all the options for output that it had as well as its configurability. I was wondering if there is something available that somebody has used and could recommend.

If this belongs in another forum please feel free to move it.
