[Qgis-user] Preserving geometry when batching joins

[Nicolas Cadieux]

Hi,
Once you have joined the geometry file to the matching attribute file, you should be able to save that as a shape file.  If you can’t figure it out, put a sample on the next email.

I've had some success, in that the batch interface to join allows me to list the input layers, fields for the joins and the output file names very easily, but I can't work out how to preserve the geometry of the points. The only file type listed that I can save are DBF / XLSX / CSV / ODS files, which will only preserve the joined tables not the geometry.
