Q: r.fill.dir blocked I am trying to fille a DEM downloaded by Geobolivia http://geo.gob.bo/.
The r.fill.dir  module in QGIS/GRASS toolbox blocked few minutes after I launched it for the DEM. It is very strange as, for instace, r.watershed module works perfectly.
How can I solve this?

A: If you have SAGA installed, try to use Fill Sinks as an alternative, and see if this tool can solve your problem. The tool can be accessed from Processing Toolbox -> SAGA -> Terrain Analysis -> Hydrology -> Fill Sinks.
