In addition to having the opportunity to decline upgrading a file on open, this add-in also allows you to report on the version of a file without opening it, or to report on the versions of all Revit files in a folder.
|The Confirm Upgrade message box when opening a file that's in a previous version|
|Report on a single file without opening it|
|Report on all files in a folder|
This add-in is free and Pay What You Want. Harry Mattison, author of the Boost Your BIM blog, has done some good works for the Revit community, most available for free. I suggest that, if you can, you show Harry some love with a PayPal payment. I will, and I'll show him a little more with his second Revit Add-ons Editor's Choice award. Congratulations Harry, and thank you!
For more information on the free File Version Reporter add-in, see the Boost Your BIM blog.
