The ONLY way I can access the "raw" files is in camera. DPP4 is returning error messages that it only supports raw burst mode files WHILE TRYING TO OPEN THEM. The files that I copied over to my computer couldn't be read so I transferred them back to the SD card to attempt to read them with my camera. THAT DID NOT WORK. So we have TWO problems. Copying files to a pc strips them of their identification as Raw Burst files. That's one. I have about SIX THOUSAND photos locked in limbo. YES I DO. I shot for two days while emptying my cards to continue non-stop shooting. ALL THAT WORK IS RUINED. Now DPP4 won't even recognize the files ON THE CARD. I need, right now, a way to extract the photos. I need to know what ID element was stripped when I copied cards to computer. I need DPP4 to work and I NEED TO BE ABLE TO COPY FILES TO MY COMPUTER TO WORK ON THEM THERE> EXPECTING ME TO EXTRACT PHOTOS WHILE ON A SHOOT IS BEYOND RIDICULOUS. My return window is closing so I need answers as soon as possible or this thing is going back and I'm buying the OM1 where Pro Capture DOES work. Please don't tell me to reinstall anything I am NOT an idiot. Been there done that. Thank you.
I understand that you are annoyed with your situation but can you give a better description of what is happening. You say that DPP4 reports that it "only supports raw burst mode files" yet from your post it would seem that you are using raw burst mode, so what exactly is the problem ? In future I would suggest that you check that your download and processing setup is working before you shoot 6 thousand photos.
I would sit down a take a deep breath, I can see your super frustrated, but I am not sure how much research you have done considering your level of frustration. Please never move files back and forth between any digital camera, it does not matter if it is Canon, Nikon, Leica etc.... You can COPY off card the whole directory or a single file, but trying to move the files or go back to camera is stated as a no-no by most manufactures and will likely mess up the formatting and structure. So I am not surprised things went sideways when you tried that. You will have to low level format the card you tried putting files back onto and messed up. Now I am not sure which version of the DPP4 software you have but there are two new versions listed on canons site here to coincide with the r7 release. Also the introduction of raw burst mode, Canon created an additional tool for DPP4. (Raw Burst Image Tool) https://cam.start.canon/hy/S002/manual/html/UG-05_Synthetic_0050.html Because the CR3 file contains all the images in the burst inside it you need to use the tool to select and extract the image, you cant just see all the files inside the compressed CR3 natively without using the tool.
