I am using a DEM and using menu Raster > Terrain analysis > Hillshade. When I type a simple output file name "MyHillshade" and then click "OK", I get a two-part error message that says:
"GDAL provider: Cannot open GDAL dataset MyHillshade.tif: `MyHillshade.tif' does not exist in the file system, and is not recognised as a supported dataset name.
"Raster layer: Provider is not valid (provider: gdal, URI: MyHillshade.tif"
How can I repair this situation?
