Why does render a Jupyter Notebook (.ipynb) creates the _freeze directory

[rgaiacs]

Description

Given any Jupyter Notebook (we will called our file index.ipynb), when I run quarto render index.ipynb --execute, Quarto will

1. update the content of index.ipynb with the output of the code cells
2. create and populate the _freeze directory

Why does Quarto creates the _freeze directory?

From my experimentation, the content of the _freeze directory is ignored for Jupyter Notebooks.

I cannot reproduce.

Did you set freeze somewhere in your project?

@mcanouil Thanks for the answer.

Yes. I forgot that _quarto.yml had

execute:
    freeze: true
