previously stored as a QGZ file it just shows a completely blank project<br>
(and no kind of error messages).<br>
<br>
I can then use 7zip to unzip the qgz file and extract a fully functional qgs<br>
file showing my whole project as it should look  :-) <br>
<br>
An example of a qgz files showing a blank project is here:<br>
<br>
Knudepunkter_ogt_påstigere_v3.qgz<br>
<<a href="http://osgeo-org.1560.x6.nabble.com/file/t202356/Knudepunkter_ogt_p%C3%A5stigere_v3.qgz" rel="noreferrer" target="_blank">http://osgeo-org.1560.x6.nabble.com/file/t202356/Knudepunkter_ogt_p%C3%A5stigere_v3.qgz</a>>  <br>
<br>
and when I unzip it with 7zip I get this fully functional qgs file:<br>
<br>
Knudepunkter_ogt_påstigere_v3.qgs<br>
