Is it possible to delete a file (always with a diffenernt name) in a static folder via dispatch?

I use Dispatch to delete an existing PDF in our "released" folder before copying the new PDF of the same name.  For some reason when copying a PDF from the Vault to a network folder it will not overwrite an existing file.  Anyway here is the Dispatch script I use, maybe it can help you with ideas.  I get the name of the file (%NameOfSelectedFile%) from the file I run the script on (i.e. approve).  You can also parse the filename to remove the extension and add whatever extension you need.
