     *
     * A media model also has a file path, this however doesn't have to be the same as the virtual path
     * and in fact most of the time it is different. This is because the location on a hard drive or web
     * drive should not have any impact on the media file/media structure in the application.
     *
     * As a result media files are structured by virutal path in the app, by file path on the file system
     * and by Collections which can have sub-collections as well. Collections allow to reference files
     * in a different virtual path and are therfore similar to "symlinks", except that they don't reference
     * a file but create a new virtual media model which groups other media models together in a new virtual
     * path if so desired without deleting or moving the orginal media files.
