Just a short note for all those using ACDSee the new version 7 allows reading of RAW data. I have got it and tested it on Nikon NEF files and it is OK except that it takes a little more time to load. The usual file format is pretty fast. I think is is better than Ver 6 which was buggy. I believe it can also read Canon raw file data (not sure as I do not have Canon, maybe others can test it).
