# Write Binary File

The Write Binary File node is used to write a file to the host machine that runs n8n.

💡 Keep in mind

  1. If you are running n8n in Docker, your command will run on the n8n container and not the Docker host.
  2. This node will look for files relative to the n8n install path. It is recommended to use absolute file paths to prevent any errors.

# Node Reference

  1. File Name field: This field specifies the path to which the file should be written, along with the file name.
  2. Property Name field: Name of the binary property to which to write the data of the read file.
