QGIS uses the GDAL/OGR library to read and write vector and raster data
formats. Note that not all of the format listed below may work in QGIS for
various reasons. For example, some require external commercial libraries or
the GDAL installation of your OS was not build to support the format you want
to use. Only those formats that have been well tested will appear in the list
of file types when loading a vector or raster into QGIS. Other untested
formats can be loaded by selecting *.*. 

\section{OGR Vector Formats}\label{appdx_ogr}
