I copied the Nikon nef Plugin from PS 7.0.1 into an extra plugin folder for PS CS. When I select this folder in PS CS it allows me to import modified Capture 4 files into PS CS and bypasses the PS CS plugin. It operates like PS 7.0.1 which I prefer some of the time. When not selecting the extra plugin it acts normally. I have the trial version of PS CS now and will buy the upgrade next month. Will this have any adverse effects on the upgrade. Thanks, Tom
