You can also text-view your DWG file and look at the string at the beginning of your file. Or you can use the DWGinfo utility available at www.cadstudio.cz/download. See also the DWGintVer utility - www.cadstudio.cz/download.

To visually identify .DWG file version by its icon in Windows Explorer you can use the DWGicon shell extension (see http://www.cushat.co.uk/fw/di/ [URL verified 9/2004]).
