Around 5 years back (where did that time go?), I posted about a free right-click Explorer extension that gives you some useful information on Revit files at a glance. CTC continues to update and provide that extension for free as part of its “BIM Project Suite”. All you need to do is:
install CTC BIM Project Suite
right-click on any Revit file to view its version and properties
This works for family RFA files and RTE files as well, and will give you an option to open in the actual file Revit version, or in any newer version you have installed.
Download: You can get the latest version of CTC BIM Project Suite on the App Store at this link.
The plugin ribbon will be installed in Revit versions 2017, 2018, 2019 and 2020.
Note: Seems like the “Open In” function will offer you any versions of Revit installed on your system, that are same as or newer than the file itself:
Revit Properties is now available within the CTC BIM Project Suite download, and runs outside of Revit. This user interface provides access to basic data about Revit project files, family files, project template files and family template files.

This is a free tool that does not have licensing requirements
