Thank you so much. I downloaded it when I read this, and love it.

Irfanview has opened every raw files I have thrown at it. It doesn't have much processing power, though, although it can do a lot of other things.

There are several FREE Microsoft Window downloads that will allow you to view all RAW (whether Nikon or Canon) natively in Windows. I use these for general viewing but I use Lightroom and Photoshop for my processing/editing.

Canon also has a windows codec available that will show thumbnails and will allow viewing of raw files. Its part of the Digital Photo Professional https://www.the-digital-picture.com/News/Default.aspx?Cat=Canon-Digital-Photo-Professional. They no longer have it as a separate download.

Perhaps you need an update to windows but my Canon RAW files from 3 different cameras plus my son's all are view-able on windows both in explorer and in photos

Just import them with LightRoom.
A. In the Library, use the right arrow key to advance from first photo to next.
B. If you like it - do nothing except hit the right arrow again.
If it is a bad focus, bad composition, blank, whatever, and you dislike it - hit the X key (to mark as rejected) and then the right arrow.
If you hit X and change your mind, hit U to Unflag it.

C. When you get to the last frame, hit Ctrl-BackSpace
When LightRoom asks "Delete from disk or just catalog?" Choose Disk and you will be free of them forever.

No need to shoot the JPG/RAW and you save time by not previewing them.

Check out Kelby's books on Adobe LightRoom. Mine is for LR4 (where I started) but the only things that change over time are that LR adds features
or drops some you never even used. You can probably get a used copy for cheap or borrow it from the library.

I do recommend FastStone Image Viewer as a good way to look at raw. It handles everything I have ever thrown at it and I usually run it
while in LR so I can toggle back and forth to see the processed jpegs after I export them. I use it to move or downsize photos to Dropbox, folders I am creating for a project, whatever, and it is simple and reliable.

I just double click the raw file and it opens. Comes with Windows.
Real easy just do it.
You can't actually see RAW in that all programs have to do something to the RAW data to make it visual to the human eye.

My win 10 laptop allows me to view but not alter Canon raw files.
I generally just upload them to Lightroom but noticed that they are also visible in Photos ( Microsoft program ).

Windows 10 can view RAW photos. You may have an older version that needs what’s called a codex file to do that. It’s a free download from Microsoft. Google it.

I use Windows 10 with all the latest updates and I can view Canon raw files for all 4 of my Canon cameras in the Preview Pane of the built in Windows File Explorer, and in Windows Photos, or Windows Photo Gallery. You have three built in options. You may need to download a Codec, but I don't recall doing so.

Faststone is good and free. I use it as a fast viewers to show someone a few photos without going into lightroom....... Never to do what you want .... Just import into lightroom..... Mark the ones you wish to delete..... Then delete all at once.... One import, one view.

You can download codecs from Micro$oft that will permit the display of raw files in Windows Exploder, Windows Photo Viewer, Photos, and other M$ widgets in the same manner JPG and similar files are visible. If you have a new camera with a new raw format, the codec may not be available yet. With that caveat, it's worth a search on the M$ site.
