Error message on import - Darktable

I am trying to copy and import images from my cameras SD card. I am using the same method as I have used previously. I am getting an error message and I am unsure what it means. Help would be appreciated.

are there two files with the same name? that’s my guess

Are you sure about the double backslashes? I think I use forward slashes even on Windows. Does the whitespace in the folder name need escaping?

They work.

Not sure. JPG and RAW of each but shouldn’t be a problem.
