[Qgis-user] QGIS Shapefile Structure (?)

[Alexandre Neto]

Hello Spring,

This has to do with the way qgis (GDAL) handles the feature deletion.
Instead of totally removing them (which takes longer) it mark them as
deleted.

The (not very elegant) workaround here is to save the layer to a new
shapefile using save as...

Hope it helps
