My Mac book pro from 2019 charges properly on 3 of the 4 USB c ports it has. I have tried everything to get the 4th to work. All other peripherals work on that port. When I first got it, all ports worked. I feel this persona pain.

Are these files that need renaming? You could open the terminal cd to the directory.

for filename in $(ls *.mp4); do
  if [[ "$filename" =~ some_file_match*.mp4 ]]; then
    modified_filename=
    cp $filename $modified_filename && rm $filename -f
  fi
done
