Hello, I've just been using Ruby for a few days, so please bear with me. I want to copy a file using the 'system' function. I am running Win NT4, SP5 and have tried: system 'copy file newfile' system 'cp file newfile' system "copy file newfile" system "cp file newfile" The copy is never performed, and the value of $? is 32512. Any help would be appreciated. Regards, Barry
