SP 2013 foundation on prem (I know it's old - but there's nothing I can do about it)
Need to copy files attached to a list item into a new sub folder on a file share - \file-srvrfile-shreunq-sub-fldr, where unq-sub-fldr needs to be unique.
From a workflow that's triggered when a new list item is created, one of the actions is to the "Copy to sharepoint", which copies to a dummy document library with another workflow which in turn copies the attachments to a share. That all works fine. Except I can't figure out how to create and get the items into a subfolder with a unique name.
Do I need to try to create a custom Nintex action using the SDK?
Any 2C welcome - cheers!
