I'd recommend that. The open connections would probably miss some of the
updates done otherwise.

In osgeo4w, you can install the "gdal-filegdb" package

Hi,
I'm looking at ESRI gdb file support and options I have. I'm doing some
tests using QGIS,
but eventually would want to use the Java API to read the files.
QGIS 3.4, as installed on my Linux distro, opens the files with the
OpenFileGDB driver. The QGIS 3.4 Windows
version of 3.4 does the same.
