Pre Revit 2013 BatchFileInfo

[stephen_harrison]

First a little background I am using Revit 2021 and programming in C#.

I have developed myself an app for updating multiple Revit families/projects etc but have recently come across a problem were families/projects pre Revit 2013 are not being updated.

I believe the issue is that "BatchFileInfo" was not introduced until Revit 2013 and this is the bases of my app to filter out files utilising "IsSavedInCurrentVersion" and "IsWorkshared".

Is there an equivalent or a workaround for 2013 files and if so any pointers would be much appreciated. 

Thank you in advance for any assistance.

You mean BasicFileInfo?

If you open a small Revit file in notepad you'll see xml near the top (part of it is double spaced due to encoding). Small so it doesn't take forever.

There have been some standalone methods created for reading this type of data:

Thank you for your response and apologies for the error. 

I have tried opening the small Revit files as you suggested and in post Revit 2013 files the information is provided as you suggested. However in earlier Revit files there is no such information.

Once again apologies if my question was not clear or I have miss understood your response but I am trying to get similar information to that provided by BasicFileInfo i.e. "IsSavedInCurrentVersion" and "IsWorkshared" but from early Revit files i.e. pre BasicFileInfo.

Thank you in advance for any assistance.

I have vague recollection this information was contained in structured storage. Therefore these links may be of use:
