Mirrored Save (Tip #2167) from Mohmed Zuber Shaikh is a utility that creates an additional copy of the current drawing on disk for archiving purposes. Load the LISP code and type Mrsave to run the command. You are prompted for a filename in a dialog box. The filename is saved a second time with the name MIRROR concatenated to the filename. Substitute that data in the source code with a network drive or other location for your archive, and this utility can result in drawings being simultaneously saved in more than one place. If you have ever lost a hard drive full of drawings, the value of this utility is obvious. If not, try not to have nightmares worrying about it.
