I don't think it affects quality one bit, a RAW file is a RAW file regardless of how you got it into C1.
At least that's been my experience with older RAW files that were already in my PC and 'fresh' ones that I download straight from the camera.
If I am mistaken I'll be happy to read and learn about it.
thanks for that........seems to make sense, guess i wondered because xp wont recognize raw files as images whereas win 7 actually shows them as thumbnails of the photos.
before i decide on a permanent download method for raw files can anyone confirm this wisdom?
