[Qgis-user] Can some one help me to convert a .bil file in a shape file?

[NYA Edouard]

Hi to every one,
SInce a certain time, I am working on a project where I intend work
with the shapefile of the .bil file available in the Harmonized World
Soil Database (HWSD). It can be found here
(http://www.iiasa.ac.at/Research/LUC/External-World-soil-database/HTML/)
The bil file es very heavy (more than 1800 MB), so I need to convert
the file so that I can trim it easily to process it for the project.
Any idea?
Thanks in advance
