I have been tasked to replace an old web server and website written in Cold Fusion 4.5/Apache with something modern without drastically changing the functionality of the current site.  Basically, I need to be able to let a user login securely to the top of an allowed directory structure and let them navigate through the directories and download files housed in those directories.  They have no rights outside of their top directory.  For example, \customer1 would be unable to see or login to \customer2's structure and \customer1\store would only have access to the store directory, not the \customer1 directory.

I would like to use an attractive, collapsible directory structure as a kind of menuing system if possible.  Internally, the directories are mapped and are populated directly from our production machines.

I am not at all locked into this method but would like to keep the organization similar to the directory structure that currently exists.  There is about 22GB in about 48,000 files that are uploaded about 9,000 at a time weekly so I really don't know of a better way of storing and organizing the files using the current system.

Any ideas and/or suggestions are welcomed.

Thanks!

No.  I know.  What I am trying to do is replicate what is currently done in CF 4.5 in DNN.  I have already set up a machine with the latest and greatest DNN and transfered all of the compatible data over and editted it to use the .Net system.  The only thing I have left is the directory structure as described and I will have my website in DNN and I can shut down the old Apache/CF server.  Doing the menu system based on the directory structure in .Net is what I am asking about.

Thanks!
