I am trying to add a geodatabase (.gdb) vector layer into QGIS but I am running into an error. It says the .gdb file is not a valid or recognized data source.
I have spoken with the agency that maintains the file and they said it should work - it works fine on their end in ArcGIS Desktop. It's a version 9.3 .gdb file.
I have successfully opened and edited other .gdb files in QGIS. I use Directory --> OpenFileGDB. I am using QGIS version 2.18.15. What could be causing the problem now?
A link to download the GDB file is here: https://vgin.maps.arcgis.com/home/item.html?id=29627d7c051a47dc8ce71b4484531ab3
Here is a screenshot of the files within the .gdb file. Is something missing?
