I just bought a Canon 90d only to find that the files are CR3 and Lightroom doesn't work. Everyone says download Adobe DNG converter. As much of a pain as those extra steps would be to begin with, after trying that, DNG converter on my PC doesn't even see the files. Windows shows they're there, but DNG shows an empty folder. And WHY, Adobe is a format that's now over THREE YEARS OLD from one of the BIGGEST camera manufacturers STILL NOT supported on your platforms? Inexcusable! I do all my editing on my phone via the Android version. What's so stupid about this struggle is that AFTER I download all the pics to my pc, then upload them to the desktop version of LR, THEN sync them to the cloud, THEN SYNC my phone AGAIN.. THEN FINALLY the files are there on my phone. WTH Adobe?! If the Android version can see and edit the file, why are you making me have to go this long round about way to access my files? Why doesn't it work directly? And WHY am I paying $10/mo for this abysmal level of service?! Three years is PLENTY long enough for you to have figured out file support. It's getting harder and harder to justify PAYING for use of your software...

The 90D has been supported for a long time. What exact version of Lightroom are you using? As far as the DNG converter is concerned, when you use it the process is to choose the folder containing the raw images but don't open the folder. If you open the folder then you will receive the message that there are no files to convert. The DNG converter functions on the folder level. The process is to choose the folder containing raw files, in your case CR3 files, and then choose the destination folder where you want the processed DNG files to be placed. When I use the DNG converter I use it in conjunction with transferring the images from the card to the computer. I choose the folder onto the card as the source and specify a folder on my hard drive as the destination. Using the converter in this manner the images are transferred and converted in a single step.
