We have a w2k advance server with a mac share. Our mac people use quark and other mac software. If we move files using windows explorer, the macs lose the association of the quark file so that it will not open automatically and it does not know what the file type is. I was reading about file type and creator codes and thought it was losing them, but if I edit the file with notepad, it appears to be in there. Any help would be gratly appreciated. Also and good doc on mac/windows info pertaining to this would be helpful.
