This question already has an answer here:
I am running QGIS 1.8 on a windows xp pc and trying to put the USGS National Hydrology Dataset (more info herefor Oregon into a project. I try to "add vector data", using directory option then selecting the unzipped folder but it says NHDH_OR_931v210\NHDH_OR.gdb is not a valid data source.
It looks like this was created in ArcGIS 9.2 -- is that the problem?
I am very new to GIS and there may be something very simple I'm doing wrong.
