    <p>RDP has this fantastic ability to let export disks from remote user's workstation to the RDP server. As far as I can tell, it is not just a windows explorer trick, but all kinds of programs can use the shortcuts "X:", "Y:", "Z:" etc... This <a href="https://stackoverflow.com/questions/9304953/copy-files-from-remote-rdp-to-local-machine">stack overflow entry</a> on RDP disk copying mentions the '\tsclient' alias which points to the machine of the RDP user. Now, it is obvious that if there are 2 or more users, they will each have their own, non-conflicting tsclient destinations. </p> <p>So, my question is this: how do I get a list of and access all remote user shared resources (disks) from a service? Ideally, if, say 2 users have connected and have shared their C: drives, i'd get a list like:</p> <ul> <li>\UserJohnDoe\VolumeXyzC - John's C drive</li> <li>\UserJaneRoe\VolumeXyzC - Jane's C drive</li> </ul> <p>Help appreciated!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
