Hi Kenneth,

If it is for an Intranet, you may want to look into the "File System 
Object" This object can be scripted from VB-script and JavaScript / 
JScript. You may need to change some security settings, like allowing 
Active X controls.

Here is an example:
http://support.microsoft.com/support/kb/articles/Q229/6/93.ASP

The FSO also has a method called FileExists, which you can use to check 
for the file.

Check out the docs for scripting and the FSO at:

or do a search for "File System Object".


Hope this helps,

Imar
