Cannot save file to host folder from Docker n8n – workflow write to disk node

Hello, I am a beginner with n8n and Docker.
I run n8n inside Docker without volumes.
When I use the “Read/Write Files from Disk” node:

  • If I set file path like C:\n8n\dane\test.txt, nothing is saved on my host disk.

  • Instead, a file file.txt appears inside n8n and I can only download it manually.

My question: How can I write and read files directly on my host disk (Windows), not only inside Docker?

Thank you for help!
