100 7345 is the folder and the file name. So on your memory card, there is a folder '100' and the file name is something like 'IMG_7345'. Lightroom uses that file name, unless you change it on import.
the file name is something like 'IMG_7345'.
… if the output color space for camera-made jpgs is set to sRGB. If Adobe RGB jpg output is set, the number becomes '_7345' (Canon cameras).
I have only ever seen the original camera numbers in LR, but I don't change the file names during import.
I would expect it to become '_MG_7345' and with a professional Canon camera like my EOS-1D X letters will be different, but it isn't relevant. The last four digits is the number, and that does not change.
Ah, excuse me. You are right. '_MG_xxxx'
