| Jan 14, 2020 at 11:39 | comment | added | Geographos | So how about the lines then? Is it possible to do? | |
| Jan 14, 2020 at 11:25 | comment | added | Joseph | You can only merge multipart polygon shapefiles together, you can't mix with multipart lines or multipart points (if that is what you were trying to do?). | |
| Jan 14, 2020 at 11:22 | comment | added | Geographos | I did it and I am still getting error: All layers must have same geometry type! Encountered a Line layer when expecting a Polygon layer. | |

What I meant was to use the Promote to multipart on all of the layers you are interested in. Then when you have all the outputs, run the merge tool. If you don't want to use the Promote to multipart each time for each layer, run it as a batch process by right-clicking it from the Processing Toolbox.

| Jan 14, 2020 at 11:06 | comment | added | Geographos | Since the "Promote to the multipart" options offer only 1 layer "promotion" I had to updated my query. | |

rebuilt query

| Jan 14, 2020 at 10:42 | comment | added | Joseph | From the Processing Toolbox. | |
| Jan 14, 2020 at 10:41 | comment | added | Geographos | Where can I find it? I just found the repository with no examples really: docs.qgis.org/3.4/es/docs/user_manual/processing_algs/qgis/… | |

You could try using the Promote to multipart tool on all your layers before merging to ensure they have the same geometry type.
