Dot Net Nuke is maturing and as such is being used on larger and larger installations. As we all know the bigger your portal the more files you have associated with it. The current File Manager system places all of your uploaded files into the one directory.

which leads to an administrative headache once you add a reasonable number of files to your portal.
The new Advanced File Manager project is addressing this limitation by enabling site and host administrators the ability to create/edit and delete folders into which they can upload, download, delete and rename files.
Site administrators will have access to their own Portal Folder such as Portals/0.
Host administrator will be able to gain access to all folders on their installation to do administratove maintenance like deleting old directories and cleaning up after a failed module installtion.
