RDWeb- access a folder on another server and allow cut and paste from local machine

I have Windows 2012 RDweb deployed and working for notepad and a custom program.

What I want to do now is to create a 'windows explorer' experience for only certain accounts to be able to cut and paste from their local desktop to the windows explorer folder.

I created a bat file that runs:

explorer \\non-rdweb-servername\folder

the folder appears successfully on the client machine when clicking the icon on the RDWEB site.  the issue is that the user can not cut and paste files from their local machine to the server folder.

I know how to make the icon only accessible to certain user accounts, and those accounts have full access to the folder.

When the bat file is initialized from RDweb, and the details are looked at, access to clipboard is checked.

Any ideas on how to make this work?

thanks.
