# Inserting QVS files in load scripts

You can insert QVS files into load scripts in Data load editor.

Inserting the script adds the system variable Must\_Include with the definition of the path to the QVS file. For example, `$(Must_Include=lib://Files (user)/test.qvs)`. You can also manually define your own QVS files to include in the load script using Must\_Include. For more information on Must\_Include, see [Include](https://help.qlik.com/en-US/sense/May2025/Subsystems/Hub/Content/Sense_Hub/Scripting/SystemVariables/Include.htm).
