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.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Just curious but do you have GDAL installed (or at least FWTools)? If so, you could run ogrinfo on NHDH_OR.gdb as a quick diagnostic. Running this at a command prompt.. C:\>ogrinfo "C:\PathToData\NHDH_OR.gdb" ..would tell you every table in the .gdb, if it's not corrupt. –  elrobis Apr 25 '13 at 21:12
If you follow the comments on… you will read that Arcgis 9.x gdb are not supported by QGIS gdal driver. Can anyone confirm that or transform the datasource to Arcgis 10 format? –  AndreJ Apr 26 '13 at 4:43

Yes! Open your OSGeo4W downloader, select advance setup, and then select gdal-filegdb under the libs tree.

There's a step-by-step tutorial here: How to get ".GDB" (Esri File Geodatabase) support in Quantum GIS (osgeo4w - qgis)

Please note that the FileGDB API Does not support Raster Images.

Thank you. I followed the tutorial and now when I try to add a vector layer, selecting directory, ESRI fileGDB and click open it says: ...NHDH_OR.gdb is not a valid or recognized data source . –  Oregonian Apr 26 '13 at 0:12
The NHDH files were created in ArcGIS 9.2 and 9.31. I guess that is why I cannot load them into QGIS. I have utilized the shapefiles instead. –  Oregonian Apr 26 '13 at 18:25
