Did you ever want to find a Media File in the Media Files folder (to save or to move it)? This used to be a real pain in the butt (remember that the media file names by default are those crazy long strings of characters), but now there is a feature called REVEAL FILE. Here's how it works:
 
A - Select the MASTER CLIP for which you want to see the media file (NOTE: this works ONLY one clip at a time)
B - Go to the FILE MENU
C - Select REVEAL FILE
D - After a moment the Media Files folder will open and the media files will be highlighted and ready for you to move or copy.

• UPDATE:

1. You may now also select a bin in the Project Window, go to the File Menu and select Reveal File.
2. You may also Right-Click on a bin in the Project Window and select Reveal File.
