The files are located under the following path:

d:\program files\nav\

There are four files: VD0CEE21.VDB dtd 3/23
VD0CF617.VDB dtd 3/27
VD0D0603.VDB dtd 4/3
VD0D1826.VDB dtd 4/12

Each of the files are over 3,000 MB which hogs space on the users hard drive. I want to be able to delete the first three files and keep the most recent file on all users hard drives.
