Windows 10: Fragmented JPEGs and corrupted folder containing .cr2 Canon RAW images files

Hello. I'm seeking help in two distinct topics. I would greatly appreciate any advice.

1. For the past years I have stored all my phone and DLSR camera pictures in an Samsung external hard drive. Lately I have noticed that some of these pictures have been "fragmented". Strange thing is, it seems to occur when Windows Explorer is loading and showing the pictures thumbnails. I want to know why this is happening, and if there is a free way to recover those pictures.

2. Ok, this seem to be a bit more complicated. On that same external hard drive, I have a folder named "RAW" containing a certain amount of .cr2 files, exclusively. I noticed that that folder contained less pictures than I remember, so I thought that some of those pictures vanished or I have deleted them. Then I tried to move from an SD card some more .cr2 files to that RAW folder, and when I tried to do that again, the message that says "there is already a file with the same name in this location" appeared. But when I searched for those files they weren't there, and I know they are not hidden.
So, I know that folder contain more pictures than it appear. Next thing I did was create a new folder, so I could transfer some of these pictures from that RAW folder to this new one. I managed to do that for a portion of those pictures and for my surprise more pictures that was invisible appeared! So I continued to move some pictures bit by bit to other folders and more and more pictures on the RAW folder continued to appear. But it came to a point that:
I - if I try to move some file from the RAW folder to another folder, all of the pictures of the RAW folder disappears.
II - if I try to delete some file from the RAW folder, every other file vanishes.
III - if i copy and paste some pictures within that folder, the same amount of pictures is seen in the folder 510 pictures. The copied and pasted pictures is there, but on the bottom of the folder some images vanishes. In another words, the folder limits the number of pictures.


Thank you very much.

Trouble with Canon CR2 RAW files


Thanks for the replies. I just had a quick chat with Canon. They're stumped too. Makes no sense why Windows 10 can handle all the existing CR2 files from this camera with no problem at all, but can't display any new ones that I try to download to my computer. I shot a test pic in JPG a few minutes ago, and that one is fine in Windows. Somewhere along the line Windows is eating the CR2, because the other photo editing software (including Canon's DPP) can't work with the new ones either.
Here's the display in File Explorer - existing CR2 files and new ones:




The Windows photo editor says it can't open the file.
Maybe I have to shoot JPG with this camera from now on, which is a pain because RAW allows you to salvage pics that might otherwise be unusable.
Thanks.

 

Trouble with Canon CR2 RAW files


I haven't experienced any problem with any .cr2 files in Windows 10, even from my old cameras. As a test I just downloaded a sample 20D raw file from THIS website (which was taken June 2005) to see if a file from someone else's camera would trigger the issue, but that too correctly shows the thumbnail in Windows File Explorer and opens correctly in the Windows Photo app.

cr2 files are already part of the Microsoft camera codec pack that is automatically updated through Windows Update, so no user action is required to display them. Therefore, I suspect that maybe there's some sort of conflict with the other software you have installed (maybe they installed their own codecs for example)? You could try setting the Windows Photo app as the default program to open .cr2 files and see if they display OK then (See Option 4 in this tutorial). Failing that, try to figure out if any of your third-party programs could be modifying Windows File Explorer and thus could be causing problems. Worst case scenario is not to go back to Windows 8.1, but to backup all your data and reset Windows 10 back to scratch, because Windows 10 does display .cr2 images and thumbnails correctly when everything is working properly.

Shooting jpeg only is fine for the majority of people, however doing so you loose the ability to change picture style profiles, white balance, utilise Canon digital lens optimiser profiles, etc. before the demosaicing process takes place. You also lose the extra headroom to recover highlight detail and the ability to output straight to 16-bit TIFF for post work, as JPEG is 8-bit with lossy compression. So depends on what people want from their images as to what format they choose to shoot in.

 

Codec for Reading CR2 Files from Canon 6D Mkii

I have no idea when Canon or Microsoft will release new codec for viewing CR2 Raw file, which Canon 6D Mark II adopts.

For the time being, you're advisable to try "FastStone Image Viewer 6.4" (freeware), which can view, edit (resize, rename, color, gray, sharpness, contrast, shadow & lightness, framing, etc.) and convert CR2 Raw files to various form (JPEG, GIF, TIFF, PDF,
etc.) via batch processing.
