When importing raw into bridge from my 5d 4 it concerts raw to dng. When importing from my eosr they become cr3. Does anyone have any idea why this is so. some view programs will open dng but not cr3

Perhaps Bridge is set to do that. See this web page:

In #3 there is a checkbox to "Convert To DNG".

If your software supports your RAW files you should not be converting to DNG.

so from what you are saying i should uncheck the dng box.

If the software supports the RAW format directly, there's no benefit from creating a DNG version of the same file.

I have just shot a new set. i didn't convert to dng. Learn something new each day. thanks

The benefit is a smaller file without loss and a universal standard.

And one will never lose a side car file!

"DNG" is a form of 'raw'.

I have to believe that "cr3" is also a form of raw.

Yes 'raw', even when written as RAW, is a collection of file types - not a type itself, as are JPG, TIF and PNG. Types DNG, PEF, CR2, CR3 and others are included in it.

Yes DNG is often called a "RAW" image file but in reality it is a container that can contain a JPG, TIF, PNG or maybe any other image file type.

The downside to converting your original RAW file (of whatever type) to a DNG file is that it is ONE and ONLY ONE interpretation of your original RAW file and perhaps not the best interpretation of your original file. The camera manufacturers do not always share the information required to interpret the information in their RAW files and therefore most software that allows you to view RAW files is created by reverse engineering the information in the proprietary RAW file and so they are different interpretations of that information. Some may be better than others at this interpretation.

Once you have deleted your original RAW file you no longer have the ability to re-interpret your original file should more advanced and better RAW editors (which include by necessity a RAW interpreter) be available.

This is of course not applicable if you are not using your RAW files but are saving as jpg or tif as these are standards that have only one interpretation.

It has been my experience over the last 5 years that that is completely false.

Which part of my comment is completely false?

Files from your 5D Mark IV should be CR2... If they are being converted to Adobe's DNG "universal RAW" format during Import, you've set up the software to make the conversion.

CR3 is a newer file type being produced by the Canon using the Digic 8 or later processors. Older software will not be able to open the newer software. You might need to update your software before it will be able to do so with CR3 files.

Another method is to use the separate Adobe DNG converter first, before working with the files in PS or LR or whatever. I don't know if Adobe has updated it yet to handle CR3, but their DNG converter can be downloaded for free. Check on the Adobe website to see if the converter is now able to handle CR3 (and specifically the EOS R files.... but since the camera is now over a year old, I suspect DNG converter can now handle them).

Before you convert everything to DNG and dump your originals, you might want to Google and read about "DNG problems". That might make you want to be sure to keep both your originals (CR2 and CR3), along with the DNG conversions, in case you ever want to work with the files with a different software in the future.
