Great free RAW editior, FastStone...

I'm surprised I didn't post this over a year ago.

I can't recommend enough FastStone Image Viewer

I don't use this to edit my RAWs, rather I use it for a quick pass on a dump of RAW from a shoot and preview and delete the ones I don't need.  I do some batch re-naming and resizing with it from time-to-time, but mainly for just proofing my RAWs.  But if you are in a bind or need something that's free, then try this one out.

+1 for this software.  I have been using it for several years as a general purpose image viewer (supports most graphics formats and RAW formats).
