I'm quite new to Qgis and have a problem which is easy to solve, I think. I've done research for hours but did not succeed.
I have a data set which contains thousands of polygons in one layer.
What I want to do:
Dissolve all polygons which overlap, intersect or touch with others. This means that there should not be any borders between overlapping, intersecting or touching polygons anymore. I don't have any helping attributes to achieve this.
Finally, I would like to export a new .shp file of the new data set.
I tried "dissolve all" but this makes just one big polygon, which I don't want. As a first step i thought to solve it with "Intersect…". But this works just with two layers. With the advanced digitizing tools I would have to select all of them manually to "merge selected features".
I'm using Qgis version 2.14.15

Try dissolving all and then split it in multi part. You have a tool for that in the advanced editing tools.
Edit: Split in single part!!!
