Hello I have a  form in Form Services in sharepoint with attachments on it.   My users would like to link directly to the attachment without opening the form.     Anyone know how to build the url to the Attachment?  

 Thanks,

Brad

The attachment is embedded in the document and there is no way to open it without opening the form.

Typically a better practices is instead of attaching it to the form just add a hyperlink to the file stored in Sharepoint. Then it can be opened directly or via a link from the form.
