This question already has an answer here:
I need to know how to install QGIS 2.0.1 for Windows 8 64 bit so it can recognize and open ESRI .gdb files.
What do i download and what settings do i change?
I have seen Installing File Geodatabase (*.gdb) support in QGIS? but the information at this link was posted two years ago, and I am looking for an update.
