I understand the basics of spatial indexes but would like to understand when exactly a spatial index would need to be re-created or updated?

The reason I ask is because when a folder was moved to a new drive on my computer rendering slowed down considerably for the shapefiles contained within it. Before moving they all had a spatial index created. After the move and after I realised the rendering had slowed I created new ones not really knowing if it would help but it seemed to work.

I use QGIS 2.18.20

  • Maybe the spatial index .qix file stores layer reference as absolute path. – artwork21 Jun 13 '18 at 12:46
  • Would changing the Save paths option to relative in the general options stop this? – AWGIS Jun 14 '18 at 11:37
  • .qix file does not store absolute paths. Your case is interesting but I fear it is hard to repeat the problem so it could be debugged. – user30184 Aug 7 '18 at 12:26
