I have full control over my SharePoint site. When I click on my document library and then click the "Library" tab on the ribbon, I see an option for "Open with Explorer" but it is disabled.
The message is vague and unhelpful:
You might not have the right permissions level to use this, you might need to select an object or item, or the control might not work in this context.
I want to be able to move documents from one folder in the library to another. This seems like an extremely minimal use-case for a document library, no? Yet it's seemingly impossible to do in the web UI.
UPDATE: I installed IE9 and enabled the WebClient service in services.msc
and the Open with Explorer option is still disabled.
