Carlos,

If you first go to 'Tools References' and set a reference to 'Microsoft
Scripting Runtime', you can dim objFSO as "Scripting.FileSystemObject" and
the folder as "Scripting.Folder".

You can also get away with just what I gave you but change the string at the
top to the folder you're actually wanting to check and rather than
generating a message box you would want to feed the file name string to
whatever code you have in your VBA subroutine.
