Awful interface! Cant view raw files! Or jpg thumbnails!

As a professional photographer, I find it very disappointing that the software does not allow you to view raw (RAF) files! I bought this drive to use when I travel so I can leave the laptop home and work from my iPad. Now IOS supports raw files, also cant not view thumbnails of jpgs even! How is a photographer supposed to quickly find a photo they need or edit their selections! an update would be appreciated!
