Files from R10 come in as JPG and Unix Executable file

[VictoriaJZ]

I am on a Mac [Mojave OS] and took shots with the R10, transferred them to my iPad [while out of town] which uploaded to Photos then when I got back to my Mac I downloaded the image files - JPGs came in as well as "Unix Executable File" and I figured that was just a RAW file [it had the same # as the preceding JPG] but when I added the extension RAW to the file it could not be opened.  Any suggestions on what is going on and how to 'fix' it == the Unix files are mostly 30mb and the JPG ones with the same number are about 15.

 that's the first preference I change in Finder = all extensions are shown = one issue is that I was. using LRC on my older iMac but now I'm using it only on my Monterey Mini and the CR2s are coming in fine but the sidecars are too and I'm not sure what that means [have asked separately here on that]
