I am trying to load an Arc/Info Binary Grid into QGIS 2.2.0 Valmiera installed in OS Windows 8.0. As far as I know, I only need to load the "w001001.adf" file contained in the "altitud" folder while keeping all other files there (Fig. 1), to see the raster and be able to work with it. There is no files names "altitud" to be loaded (as in ArcMap), and I have to load the "w001001.adf", which appears under the very same name in the layers toolbar (Fig. 2).
Conversely, when using ArcMap, we start adding the same raster data from the very same folder, and only one file with the name of the layer (altitud) appears (Fig. 3). All other files (dblbnd.adf, hdr.adf, prj.adf, sta.adf, w001001.adf, and w001001x.adf) are not displayed. One only needs to double click on the "altitud" file to load it, and this layer (and others) is displayed under the same name in ArcMap (Fig. 4).
At this point my questions are:
1) Why does QGIS behave somewhat differently from ArcMap in this respect?
2) Is there a way to load and see raster files in QGIS in the same was as in ArcMap, getting to see the actual layer names in the layers toolbar?
