Here is the macro I've used in GSA SER for the last several years:
I use GSA in a VMware image, so rather than fill that VMware up with a bunch of articles I keep them on a shared drive and simply point the macro to them. As of update 11.28 it works fine, but if I update to 11.41 it stops working and won't use the article.
Obviously the folder is properly shared and accessible since it works just fine in older versions of GSA SER, so I'm guessing this is a bug. The folder destination: \\vmware-host\Shared Folders\Dropbox\articles\ is accessible in the VMware image.
I think it has something to do with the prefix:
instead of using the traditional:
But of course the \\ just means you're accessing a network folder so it should work fine.
