Hmm, if my memory is correct there isn't. We created our own view where we showed the URL to the Media. Might have changed in later versions though.
If you double click the file, so Episerver loads up the preview/editing of the file, you can get the url by clicking the option (publish if you've made changes) button and then 'Download the file' link. It will however download the file, but you can right click the link and copy the url.
The same goes for pages, from the options button you can easily open the the page in a new tab or whatever. That's way easier than open up the global menu and then click the small globe.
I'm developing an EPiServer 7.5 site at the moment and I'm curious... Is there a way for editors to easily retrieve the URL of a specific media (ex. PDF or DOC) file in the Resource window (block/media etc. to the right)? In earlier versions (like 5 or 6) you were able to "open" a media file and then you could easily copy the URL. Now that's not an option... You can download the file but that won't show the URL in an obvious way. Thankful for help!
