Looking at the docs

If you have an adf file it sounds like you have GRID on your hands, not
a vector dataset.

"If the directory contains files with names like w001001.adf then the
coverage is a grid coverage suitable to read with GDAL, not a vector
coverage supported by OGR."

Keep in mind this list is specifically for discussing the OSGeo4W
installation tool. Questions about specific sub-products outside of the
installation should be addressed to that project.

I would highly recommend you join the GDAL mailing list
