[Qgis-user] All attribute info GONE!

[Andreas Neumann]

Hi Merryn, 

A feature in (Q)GIS always consists of geometry AND attributes. So if
your geometries are around, also your attributes should be around. If
you delete a feature, both geometry and attributes are removed for this
particular feature. 

If your attributes are gone, double check if the naming scheme is really
correct. You mentioned that you don't see file extensions in Windows.
You need to enable the display of the file extensions in the windows
explorer to see them. Double check that they have the same basename and
then just one extension (not accidentally two). 

One can delete attribute table columns in the layer properties. But I
don't think one does this by accident.

I go back to open QGIS file and I discover that the main file and associated subfiles have been deleted. I restore them from the bins but when I open all the vectors are still there but attribute tables are empty!!! If i zoom to the file it doesn't show anything. Does anyone know what she could have done and how I can fix it? Is it possible that she saved as the vector with the same name and accidentally deleted all the data existing data??
