Quarto overwrite and then deletes a notebook file with the same base name as the quarto file

[vnijs]

Description

Suppose I have a file my-file.ipynb and my-file.qmd in the same directory. I want to keep and use both files. If I now render the qmd file it seem to (1) overwrite my-file.ipynb and then (2) delete my-file.ipynb. That seems a bit destructive. I can change the names of the files but I'd like to know if there is a way to stop quarto from overwriting and deleting files in this way. Thanks

This issue has already been extensively discussed in several places. Please take a look at those discussions for more information.

• Quarto deletes the original index.ipynb file when rendering a different notebook (index.render.ipynb) with output-file: index, despite the original file being explicitly ignored in the project configuration. #10841
• Python .qmd render deletes existing same-name notebook  #8727
• [VSCode] Rendering Deletes ipynb File #4802

Which version of Quarto are you using? Note that I cannot reproduce the behaviour you described on latest Quarto CLI version.
