I am looking for DreamHost compatible software, preferably free, that would allow me to create web interface to a hierarchical listing of files available for download, such as Excel spreadsheets and Powerpoint presentations. By hierarchical, I mean that the files need to be divided into an arbitrary number of categories and subcategories.
The tricky part is that the entire thing must be limited to users with user IDs and passwords, and certain users would only have access to certain files/folders, as decreed by the administrator. Preferably, each user would only see the files/folders he/she has access to, but that is not a strict necessity.
I’m sure there has to be software that does this, but I’m not certain how to find it… any suggestions would be greatly appreciated. Thank you for your time and consideration.
