Is there any way of using FileExists or VBscript to search for a file that is not resident on the actual Web server. I tried to use this function but it returns false if I do search outside of the Web server. Any ideas on what function I could use instead. Thanks!

Even I had same problem as of Derek... The funciont returns False when tried to search files on a virtual directory which is not on the same machine as that of the IIS.

This is a good use of the file system object, but be careful if you use this function in your projects. You really should release the object with a SET fs = Nothing statement.
Also take a look at the inet transfer object for looking for files on remote systems.

I got around the boolean result being false all the time but adding Server.Mappath to the code. For example :
bFileExists = fs.fileexists(server.mappath(sFilename))
It worked for me, give it a try !

I have a problem. I have the same code or syntax and I text it run the script into my computer (drive c:\) it works. The file exists method works but when I put it on a web application, it doesn't work. Does the permission involved why it didn't work or the IIS involved?
