Solved: NWC Start Form attachment directly into SharePoint... - Nintex Community

Hi Garrett,

I tried the methods in the link, pls see my screenshot. However I am not sure if i can update items as expected since the file is saved in a folder while update items function is for a list. I can only see one file saved in the folder. Did i miss anything? Thanks vm!

Hi @mjliu 

Yes, you are correct. Items update will go to the Item List. File saved will go to SP Documents folder.

You should also be aware that the attachments are still available from the Start Event Form (NWC File Upload Storage) - where the default settings is to retain for 7 days 

You can save multiple files to SP.

Use a For-Each loop on the Files Collection.

Store a File using the Current Item

Files will be saved to a Documents folder
