DWG Columns has been updated for AutoCAD 2018 and the new DWG 2018 drawing file format.
One good news with AutoCAD 2018 is that “The file navigation dialog boxes for operations such as Open, Save, Attach and many others now remember the sort order of the column. If, for example, you sort by file size or reverse sort by file name, the next time you access that dialog box it will automatically display files using that same sort order.”
How it works in Windows Explorer / File Explorer. Show DWG properties like version, what software the dwg was created by and more.
If you only want to see the DWG version there is a freeware version of DWG Columns available as well.
