The Android's Google Photos App Won't Open .CR3 File

I have Canon M50 and I shoot RAW. And it saves the raw in CR3 format. When I copied the CR3 files to my pixel and tried to open the folder on Google Photos, it doesn't show load the images at all.

Looking on this page, there is this statement:

Making it easier to manage, share and edit your original photos (including CR3 files)* in your Google Photos library

And the written footnote:

*Offer expires and must be redeemed by May 31, 2021. Available to new Google One members only. Terms Apply.

I am using Google One subscription, but still my CR3 image files can't be opened. So in my desperate move, I renamed CR3 to CR2 extension. And voila, it works!!!! 😂

So, the only thing I need to do is to rename all those CR3 files (more than 100 images). After trying some file manager, it seems in android, it is impossible to the extension file on multiple files at once -- please let me know if you have good app that can do that. And in macbook, it is also impossible to do this using the Finder :(

So my last resort (to rename all CR3 files to CR2 extension) is by using this simple oneliner script:

# Note: this only works for filename that doesn't have multiple '.' (dot) character. 
# E.g: 
# - IMG-1111.CR3 -> works
# - IMG.AA.CR3 -> doesn't work

ls *.CR3 | cut -d'.' -f1 | xargs -I@  mv @.CR3 @.CR2

Enjoy!
