Workflow solution for checking existence of file on the server

Permanently deleted user

We have a workflow which runs from the feature description of a point.  It checks a field value, and opens a link to a new page with a document based on the field value.  In some cases I need to check for the existence of the file on our server (not one-for-one match between files in the table and files on the server).  If the file does not exist on the server, I want to stop the workflow from proceeding.  

 

How do I do a file.exists to my virtual directory?  I am struggling with how to code this inside my workflow.

 

Thanks

  There is a method in the .net io.file class called "Exists" which you can probably use as long as your workflow machine can view the target virtual directory.  You could instead use a webrequest workflow activity to check for a 404 agains the url before you provide it to the user.
