When I try to import the files from my SD card from Canon EOS R to Capture One, I regularly get an error stating: "Could not copy file to import destination. File was not imported". I don't know what the problem is. How that could be fixed?
The particular camera model Canon EOS R is supported in Capture One starting from the version 12.0.0. The supported RAW file format is CR3.
However, the EOS R with the latest firmware (1.6.0) writes some RAW files on the SD cards with a file property “locked". That is why, Capture One cannot read the file and add it to the Catalog/Session.
The workaround for this issue is to copy the RAW files to the computer manually and unlock the images by removing the checkmark from the checkbox in the properties window. Then you will be able to import images to Capture One.
