Does anyone here have any idea if there's a 64 bit Canon RAW codec available yet? All I can find from Canon or Microsoft is the 32 bit version. I need the RAW file thumbnail to show up in File Explorer & the newer RAW files made by the 70D & the G5 X etc... don't show up with windows 64 bit OS. I know I can use DPP 4x but I'd like to also see them in file explorer.

Not sure exactly what you are talking about because the thumbs show in File Explorer on my 64 bit Win box with OS 10.

Each new camera model has a slightly different version of CR2. For this reason third party Raw conversion applications have to be updated frequently with new camera support and Canon issues with each new camera an updated version of DPP. The same applies to codecs, even though a codec essentially does no more than notify the OS where in the metadata of the CR2 file the embedded jpg is located so that it can be used as a thumbnail or displayed in the OS's image viewing app. Thus codecs also need to be updated regularly, but MS doesn't give this very high priority, maybe because there are so many new cameras of all brands being released all the time. So far as I can discover, MS's last release of an updated codec was a couple years ago. MS codecs are free and sometimes Canon quietly installs a new codec for their products together with DPP, but there are also photo app companies that make a few dollars selling codecs and they, of course, try to keep them more up-to-date.

Since as Elie has pointed out all that is necessary is to know where in the file the JPEG encoded preview is located that should be really easy to manage. Simply place a pointer in a fixed position in the file for all camera versions. Then the OS only has to read the pointer and go to the correct location in the file. I really don't know why the camera manufacturers make this so hard. Yes as cameras change the location and size of the preview has to change, but they seem to want to make it as hard as possible.

Looks like Elie is right. The codec at the above link is dated 4/22/2014. I would guess a new camera or two might have been released in the last two years? (sarcasm intended).

But here's an important follow-up about the codec at the link for win 7 users (and what may be needed to make it work).

On my Win10, here's a screenshot of my Canon RAW 70D images. 64 bit.

I didn't download any special codec. However I do have a few image processing programs installed, DPP 4 being one of them. One of my programs may have installed a codec that File Explorer is using.

Thanks stathisgr but that 64bit one only fixes the 70D thumbnails. The G5 is supported but, not the G5 X unfortunately.

I was able to install on Win 10 using the link "Download it here" on the bottom of this page

I can see my Raws in Explorer

That's great Immaculens. Are you running a 32 bit version of Windows 10 ? I'm running Windows 7 64 bit & the problem seems to be that there's no 64 bit codec that supports thumbnails for my G5 X.

Thanks for the info. Immaculens. It may be be that Win 10 64 bit supports raw thumbnails natively for the G5 X. My son is running Win 10 64 bit & I'll check that out with his system.

Unfortunately, for the PowerShot G5 X, the Codec came out in 2014 - a year before the G5 X. Therefore the Codec in Win 10, or Win 7 does not know the G5 X even exists. Hopefully Canon will update the Codec .
