[Qgis-user] QGIS problem

[Юліана]

Yes, there are 5 files shown in the photo because I closed some of them;
generally, not all the files in the photo are loaded.
That's right—dragging files isn't done through the windows, but via "Layer"
> "Add Layer" > "Add Raster Layer," and that doesn't work either.
