Postgis shapefile loader 2.1 error: dbf file can not be opened

I just faced the same problem. I solved it by changing the location of shapefile. It seemed a problem of too long file name. When I moved the files up in folder tree, it worked perfectly, using the plugin.

Please check out GDAL OGR2OGR to load shapefile data into postgis

Ogr2ogr Command to import shape into postgis

ogr2ogr -f "PostgreSQL" PG:"host=myhost user=username dbname=mydbname password=mypassword" your_shapefile.shp

For details

I've had the same error. In my case the solution is also the path name. The path name must not have any special characters like ä,ö or ü.
