If you're using the Canon File Viewer Utility program that probably came with your camera, once you know which RAW files you want to covert (make your adjustments in that program when they're still RAW, so you can convert to JPG with the changes made), just highlight all the ones you're JPGing, then click the icon in the tool bar that looks like a little blue folder with an arrow pointing into it ("Save File"). When you click that, you'll get 3 options - click on "Convert and Save In File". Then, specify a folder to save the JPGs in, choose "JPEG" under "Convert from RAW to Other Format", enter new file naming, if you want to, then click "OK". It takes a while to get done, but you'll have JPGs saved into a new file, which you can then work with as needed. Plus, you'll have your original unaltered RAW files still where you're storing them (I prefer to store them on CDs and work with them from there).
