A list of one or more files to be loaded into QGIS at startup. Files must consist of a data format supported by QGIS and only disk-based formats can be loaded using this method. This includes shapefiles, MapInfo files, and most raster formats. Data stores that cannot be loaded in this way include PostGIS layers in a PostgreSQL database and GRASS vector/raster data.
