Put file into volume within Databricks

Hi! From a Databricks job, i want to copy a workspace file into volume. how can i do that?

I tried

`dbutils.fs.cp("/Workspace/path/to/the/file", "/Volumes/path/to/destination")`

but got

Public DBFS root is disabled. Access is denied on path: /Workspace/path/to/the/file

Is this the recommended way to put file into Volume? prefer not to go with the API way for now.

Hi @lauraxyz,

You can give it a try using: dbutils.fs.cp("file:/Workspace/path/to/the/file", "/Volumes/path/to/destination")

by adding "file:", i'm able to put File type into Volume, but for Notebook type, i would get following error:

ExecutionError: An error occurred while calling o460.cp. : java.io.FileNotFoundException: /Workspace/path/to/the/file (Operation not supported)

How does it work for Notebook type of file? I tried replace "file:" with "notebook:" or "Notebook:", neither works

Let me try it on my end and get back, looks like we need to upload the destination location to a dbfs location first then a volumen.

Found the reason! It's the runtime, it doesn't work on Databricks Runtime Version 15.4 LTS, but started to work after changing to 16.0. Maybe this is something supported from the latest version?

I do have one question, i think this post is the best suitable. I do want to override a wheel files into a Volume i do have already created in my CICD process. I do have something like this:

- ${{if parameters.filesPackages}}:

- ${{ each filein parameters.filesPackages}}:

- script: |

ls ${{ file.sourcePath }}

databricks fs cp ${{ file.sourcePath }} ${{ file.targetPath }} -r --overwrite || exit 1

displayName: "Deploy package ${{ file.name }} to Volume"

Being file.targetPath = /Volumes/1/2/3
