Why do RAW+JPEG photos from my Canon 1100D show up as two JPEGs on my PC?

I’m shooting RAW+JPEG on a Canon 1100D. After copying the photos to my Windows PC, I see two files for each shot, but both appear to be JPEGs and look the same size. Where is the RAW file, and why isn’t it showing correctly?

It is possible that your version of Windows in not up to date and does not contain the codec's required to support the Canon RAW format. Windows did not, until recently, have this built into the system.
Try the Microsoft Codec Pack, which should give you the ability to show and use the RAW files.

Also, if you have the necessary RAW support, in this case, .cr2 files, both images will display similar images in preview. The RAW file embeds a JPG image within it, in order to display a preview for use in such things as Windows Explorer or Mac Finder. If you have Windows configured to hide file extensions for known file types, you may see a RAW file behaving as a JPG. If you do not see .jpg at the end of the file, this may be the issue. Turn on file extensions to confirm that these are indeed .cr2 files.

Generated from our catalog & community — verify before relying on it.
Most likely the camera is recording a RAW file correctly, but Windows isn’t displaying it properly. Canon RAW files from the 1100D use the .CR2 format, and on some Windows systems they can appear with a JPEG preview or be misidentified if RAW codec support is missing. RAW files also contain an embedded JPEG preview, so they may look similar in thumbnails.
Check whether file extensions are hidden in Windows—one file may actually be a .CR2 even if it looks like a JPEG. Installing Canon or Microsoft RAW codec support can also help Windows recognize the files correctly.
If you’re copying files by dragging them from the camera in Windows Explorer, that can also cause confusion. One community answer reported that using Canon EOS Utility to transfer the images made the RAW+JPEG pairs appear correctly as .CR2 plus .JPG.
So the issue is probably on the PC/import side, not the camera. Verify the camera is set to RAW+JPEG, show file extensions, and try importing with EOS Utility or RAW codec support installed.
