Quick and simple RAW file viewer/editor

A useful piece of free software is FSviewer I recommend you choose the portable version as it can be run from any location even a memory stick. It's great for fast viewing raw files rather than clogging up your memory cards with additional jpegs. It enables you to view them very quickly to delete the rubbish, oh, and you can do a small amount of editing. Very handy for those netbook moments.
