Re: [Qgis-user] adding a layer from a zipped file
Hi Richard,
Your "wild guess" is exactly right. I tested it. I copied file
"GardenA.qml" into the same folder where "GardenA.zip" is located. Then
told QGIS to add vector layer "GardenA.zip". It added layer "GardenA"
using the correct color and labels. A similar test added layer
"GardenAtrees.zip" with the correct svg symbol.
You've solved the mystery. THANK YOU.
I'm not happy with the resulting layer name ("GardenA - GardenA.shp"
instead of just "GardenA") so I'll have to change all the layer names.
But I can write a Python script to do that.)
I've never used geopackages. Something new for me to learn.
Cheers,
Steve

Wild guessing here (not tested).
I think: GDAL is responsible for loading the data from shape OR zipped
shape
QGIS is responsible for loading of a corresponding qml file.
Normally, when QGIS (using GDAL) loads foo.shp, it will check if there
is a foo.sld or foo.qml NEXT to it, and if so, uses it to STYLE the data.
Now if you zipped foo.shp+files into foo.zip...
Maybe QGIS is clever enough to ALSO look INTO the zip (and if not,
this would be a nice Feature Request...)
But else: try to put foo.qml next to the foo.zip
But if you zipped the files into bar.zip...
Then I would try to put a 'bar.qml' next to it (and hoping that QGIS
decides that it has the same 'base name'.
If all that fails: I would create a Feature Request for it (or start
using Geopackages ...)
Note that using geopackages, you also have 1 file, and you can save
style INTO the geopackage (and even put more layers+styles into it etc
etc).

Richard Duivenvoorde

Hi Phil,
Thanks for your reply. This morning I updated my QGIS from
version 3.16.3 to version 3.22.7 . With complete optimism, I
reloaded several layers from zipped shapefiles, but alas the problem
remains: polygons appear in random colors and without labels and
point layers have dots instead of the svg icons they have when I load
the same layers from the un-zipped six shapefile files. When I
examine the zip files with Windows File Explorer, I see the .qml
files are there and uncorrupted.
I'm using a five-year-old plain vanilla Dell desktop running
64-bit Windows 10.
I did the zipping with Thunderbird's Archive. Then, separately,
zipped one layer with Windows File Explorer zipper. Same result.
Am I doing something wrong? Shall I try updating to QGIS 3.24
? Is it "stable"? What does it mean that version 3.22 is "stable"?

Hi Stephen,
You might let us know your operating system and which version of
QGIS you are using because it works as you desire in the latest
development (3.24.3) and Long Term Release versions (3.22.7). It
may just be a matter of updating QGIS.

*Subject:* [Qgis-user] adding a layer from a zipped file
When I write a layer as a shape file, it appears on my C: drive as
six files, all with the same name but different extensions. Then I
zip those six into a single file (xxx.zip). When I reload that
layer from the zip file (Layer > AddLayer > VectorLayer > File >
Dataset > xxx.zip), QGIS is almost smart enough to restore the layer
correctly. The polygon features are in the right place and their
attribute table is correct. *My problem* is that it ignores one of
the six files, the "style" file (xxx .qml) which specifies color,
labeling, and symbol). Do I have to unzip before restoring layer
xxx ? I know I could open the layer's properties and use Style >
Load Style from file xxx.qml . But when I'm restoring several
layers that's a lot of key strokes (and may require that I unzip).
It seems to me that this shouldn't be necessary. [I encounter the
same problem with point layers and polygon layers.]
