Dim fso as Object

Set fso = CreateObject("Scripting.FileSystemObject")
If (fso.FileExists(filespec)) Then
    debug.print filespec & " exists."
Else
    debug.print filespec & " doesn't exist."
End If

Both of the above methods work well.

If you are only checking to see if the file exists the first method is faster than creating the scripting object then dropping it. If you are going to do a lot of file stuff then use the second method and keep the file system object around in your program so you don't need to keep recreating it.

If you are going to read from the file you can also just open it and check for an error (this is the fastest way if you are going to use the file when it exists)

on error resume next
open "yourfile" for input as #1
if err=0 then
   '
   ' your code goes here
   '
   close #1
end if
