I have noticed this for a long time, but it became a ral problem when I accidentally did not save a drawing before exiting. I am using 2016 Design Suite just moving up from 2011 with Raster Design. It has been the same situation on both. I don't know if it is an AutoCad Problem or Windows Eplorer problem but I can work on several drawings, save them and go into Explorer and the date still shows the file to be several weeks old. It is the same for DWG, TIF and BAK files. It only seems to happen with AutoCad files as all other programs update a modified file.
Any suggestions?
