Hi Kirk- I see a work-around. I only shoot RAW and if you set the Ingest option under Filter files to "Copy RAW photos only" it will ignore the ML files. If you have it set to "Copy Raw and non-Raw photos", it ingests the ML files as well. ML includes files with .fir, .pdf, .dat, .bin, .cpg, .cfg, .lut, .tra, .bmh and one with no suffix. It does have a few .bmp files which are of course image files and would be a problem to filter out.
