I honestly have no idea why ppl have an issue with the OP trying to view or even email his RAW file. I got a brother-in-law who has a 10d and if he wanted to see my RAW file, I would email or file transfer to him with no issues. If he couldn't view my CR2 file, I would tell him to try out Digital Photo Professional (DPP). So, why its anyones business why isn't helping the OP with the issue. If he/she sends the file (if it can be sent due to its size) and the recipient can't view it, then, thats his/her problem. At that point, I would tell the OP to use DPP and convert to either Tiff or Jpeg. Then again, I would rather help instead of complain that the poster doesn't understand RAW.
As for the help side, what operating system are you using? Did you download the filter from Canon http://www.usa.canon.com …d=17316#DownloadDetailAct
? In the "select OS" dropdown box pick your Windows OS. It will show you the RAW Codec 1.4. Download that. When you download it, double click it and install. It should tell you to reboot your computer. Reboot. When its boots up you should be able to open the location you saved your RAW files and you will see them as thumbnails. If you aren't, you may need to Right-click some free space within that folder and select View/thumbnails. That should work. If not, it might be either your files are busted for some reason, or, your OS. Hope you get it worked out.
Or you could just view them all in DPP and remember (or write down) the file names to send. Happy shooting.
