Has any method can replace BasicFileInfo.Extract() ?

[Anonymous]

About "BasicFileInfo.Extract()" In "API Changes 2019"：from a version of Revit prior to Revit 2019 will result in an exception if it is called on a Revit 2019 or later file. Is there another way I can get version information without fully opening a Revit file?

You mean you want to obtain information from a Revit file saved by a later version of Revit, later than the one you are using to run the API? No, I do not believe that Revit can open files from later versions, only earlier ones. I would suggest running the add-in calling the BasicFileInfo functionality in the latest version of Revit. Depending on what information you are trying to retrieve, you might also have more luck trying to retrieve it without using Revit at all:

  Thans for your replay. I have got lots of helpful info from your personal blog in past work.

  Your reply made me aware of my mistake that I tried to get information about the new version file with the old version API . 

 Thanks for your help again and I feel very luck for it.
