[font color=\'#000000\']I don't bother keeping the THMs. The Adobe Raw converter can process the CRWs by themselves just fine, and the browser shows all of the shooting data I care about, like ISO, shutter speed, aperture, lens used, and focal length setting of the lens if it is a zoom. The only change I have anyu interest in applying to the RAWs is a batch rename to chronologically order files shot with multiple cameras and give them all the same naming convention. This works fine for me, your mileage may vary.[/font]
