hai one day i had drawn a autocad diagram....i log in a server type......my friend said he accessed the my shared folder and instead of coping the file .he had simply opened the file in autocad 2000 and copied the diagram alone and pasted in his....new file......the next day ...people stated speculations abt that the people working in the server can find the operation he has done,.......is that possible
