How to change all paths in Houdini scene file

The Problem:

I need to change all paths in a Houdini scene file due to a drive change - oh no! All my nodes are invalid, my scene is broken and everything is on fire. Or is it? No its not, i'll tell you why:

The Fix:

 1.) Windows > Hscript Textport

 

 

2.) Type opchange YOUROLDLOCATION YOURNEWLOCATION

(press enter)

And there you go, all nodes referencing YOUROLDLOCATION will have search'n'replaced it with YOURNEWLOCATION. Magic. Everything fixed. :)
