Every time I have seen a screen capture of the RED files in a directory they are shown in what in Windows is called the "detailed view"

Using the MAC Pro and the Apple operating system can the R3D and/ or the quicktime reference files be shown as thumbnails in the directory? ie:the first frame of the footage? I would think this would be much easier than the long RED filenames.

I'm a PC guy changing over to Apple so I'm not sure how the MAC can represent files in a directory.
