Open dwg in TrueView - how do I know which version of AutoCAD was used?

[Anonymous]

Does viewing in Trueview verify the conversion from one version of Autocad to another???  

I have asked the Contractor to resave the AutoCAD 2014 files to 2012 because the 2012 version is supported by the field.  How can I verify that the dwg files were resaved to 2012 when opening in TrueView?

You can open a DWG file in Windows Notepad, and the first six characters will show the DWG version, albeit a bit more cryptically. (Note that larger DWGs can take a while to open in Notepad.)
The AC10xx versions are as follows:
AC1015 = AutoCAD 2000
AC1018 = AutoCAD 2004
AC1021 = AutoCAD 2007
AC1024 = AutoCAD 2010
AC1027 = AutoCAD 2013

Or Use Notepad's Find feature and search for a u t o c a d (include a space between the letters).

Thanks!  How do I open the file in Notepad??? I'm not familiar with AutoCAD/TrueView at all other than the real basics...

My next question is that on a previous project, when we opened the dwg files in AutoCAD 2012, some files were corrupted.  Will TrueView open corrupted files?  What I don't want to do is to get 2012 AutoCAD and open all the dwg files to verify that they are not corrupt.

Start NOTEPAD first then drag and drop any DWG file on it https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=where+is+windows+notepa...
