Recently Visage was updated merging the Image Manager and File Manager into one 'Media Manager', with this update we have lost the ability to preview files in a box on the left hand side and the link for the file/s no longer displays.
To locate the file path to use as a link follow these steps;
Open any page and select to insert link
Search for the file you require a link for
Once you select the file, copy the URL without the ../../
You can then use that URL to link files.
