I am not familiar with autocad and inventor drawings but have some that I need to inventory.  The issue is that I need their drawing create date, not the file system create date.  Does anyone have any tips one the best way to go about getting a list like that?  I have the files in a directory on a windows platform.  I may be able to combine them in one folder, but the ideal would be to scan a directory and spit out a list of paths, files, drawing create dates, and last change dates. 

If anyone has any tips, advice or ideas that would be helpful, I would be most appreciative!
