I don't think that I was clear. I am looking for HOW set permissions to files and
folders appropriately, given the scenerios below, so that the appropriate individuals
can access the files to read and write.

For example I could start IIS right click on a folder, go to directory
security and enable anonymous access. This is probably not the
best idea especially if files are only read or written by select individuals.

What are other methods are available.

 Scenerios I am looking to solve.

1) Attach an XML file to a WebControl TreeView
2) Anonymous access for pictures
    a) Read files that are in the virtual directory
    b) Read files that are on another disk partition
3) Grant read / write permissions to individual files based on a person or group
    and allow them to read / write..

Thanks,
Dave
