Hi, Even if you have special COPY permission in NTFS, any user with READ access will open the file and just use Save As to save it anywhere, or just write a small code, possible in any programming language, to read file and write a new file. So COPY thing is useless, MS is intelligent enough. Regards, On Fri, Jun 20, 2008 at 12:39 AM, Michael P.
