Merge vector Layer II Merging multiple vector layers to one layer using QGIS II QGIS

The merge layers tool merges features from multiple layers into a single layer.

Step-
The Merge vector layers function, available at Processing Toolbox-Vector General-Merge vector layers, provides an algorithm that combines multiple vector layers of the same geometry type into a single one. If the attributes tables are different, the attribute table of the resulting layer will contain the attributes from all input layers.
