How do I crop RAW format images?

I use a canon 40D. I shoot raw and I dont know how to crop some images while still in raw. I use Canon's software that comes with the camera to process Raw images. Thanks in advance for your help. I really appreciate it. |||If your camera came with software it should give you the option to crop in the raw format.





If not, you should definitely use photoshop, which will give you that option no matter which format you are in, and then you can also save it in raw, jpg, tiff... which ever format you want or need.
