This is above me, so I'm asking for more detailed instructions. I've created a data connection in my Infopath form to save attached files to a SharePoint library. It throws an error when there are duplicate file names. From a blog I read to create a new data connection for the WSD web service, using the CreateFolder option. I did this successfully. The blog then states "You can then execute the CreateFolder method. For the input parameter, basically it is just <document library name>/<your desired folder name>." The blog is old, so I'm not sure I can contact the author, but will try there as well. How exactly do I execute the CreateFolder method?
