How can I achieve this?

I'm currently working on moving a python .whl file that I have generated in dbfs to my repo located in /Workspace/Repos/My_Repo/My_DBFS_File, to commit the file to Azure DevOps.
As Databricks Repos is a Read Only location it does not permit me to programmatically copy the file to the Repo location.
However, the UI provides various options to create or import files from various locations except dbfs.
Is there a workaround to actually move dbfs files to repos and then commit them to Azure DevOps?
The documentation says:
Databricks Runtime 11.2 or above.
In a Databricks Repo, you can programmatically create directories and create and append to files. This is useful for creating or modifying an environment specification file, writing output from notebooks, or writing output from execution of libraries, such as Tensorboard.
Using a Databricks cluster with Runtime 11.2 solved my issue
I need to automate a way to download Azure Databricks notebooks using Python to my local machine. Please let me know if there are any ways.
Yes, there is an API endpoint to export a notebook.
Refer to the documentation: https://learn.microsoft.com/en-us/azure/databricks/dev-tools/api/latest/workspace#--export

I am trying to create my first pipeline.
So my task is to create a pipeline with python, which purpose is to upload CSV file from a local system to AWS S3 Bucket.
After that I need to copy the data from this CSV file into PostgreSQL table. I checked AWS documentation (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/PostgreSQL.Procedural.Importing.html#USER_PostgreSQL.S3Import ). I follow the instructions but still get an error when i try to run the code from the tutorial in my python environment.
The Questions: is it possible to achieve it with python?
Could someone share a little bit knowlege and python code how he do it?
I installed the CLI rest api and now I want to save a test file to my local desktop. This is the command I have but it throws me a syntax error:
dbfs cp dbfs:/myname/test.pptx /Users/myname/Desktop.
SyntaxError: invalid syntax
dbfs cp dbfs:/myname/test.pptx /Users/myname/Desktop
Note, I am on a Mac, so hopefully the path is correct. What am I doing wrong?
To download files from DBFS to local machine, you can checkout similar SO thread, which addressing similar issue:
Not able to copy file from DBFS to local desktop in Databricks
OR
Alternately, you can use GUI tool called DBFS Explorer to download the files on you local machine.
DBFS Explorer was created as a quick way to upload and download files to the Databricks filesystem (DBFS). This will work with both AWS and Azure instances of Databricks. You will need to create a bearer token in the web interface in order to connect.

Hope this helps.
Normally I use below URL to download file from Databricks DBFS FileStore to my local computer.
*https://<MY_DATABRICKS_INSTANCE_NAME>/fileStore/?o=<NUMBER_FROM_ORIGINAL_URL>*
However, this time the file is not downloaded and the URL lead me to Databricks homepage instead.
Does anyone have any suggestion on how I can download file from DBFS to local area? or how should fix the URL to make it work?
Any suggestions would be greatly appreciated!

Method1: Using Databricks portal GUI, you can download full results (max 1 millions rows).
Method2: Using Databricks CLI
To download full results, first save the file to dbfs and then copy the file to local machine using Databricks cli as follows.
dbfs cp "dbfs:/FileStore/tables/my_my.csv" "A:\AzureAnalytics"
You can access DBFS objects using the DBFS CLI, DBFS API, Databricks file system utilities (dbutils.fs), Spark APIs, and local file APIs.
In a Spark cluster you access DBFS objects using Databricks file system utilities, Spark APIs, or local file APIs.
On a local computer you access DBFS objects using the Databricks CLI or DBFS API.
Reference: Azure Databricks – Access DBFS
The DBFS command-line interface (CLI) uses the DBFS API to expose an easy to use command-line interface to DBFS. Using this client, you can interact with DBFS using commands similar to those you use on a Unix command line. For example:
# List files in DBFS
dbfs ls
# Put local file ./apple.txt to dbfs:/apple.txt
dbfs cp ./apple.txt dbfs:/apple.txt
# Get dbfs:/apple.txt and save to local file ./apple.txt
dbfs cp dbfs:/apple.txt ./apple.txt
# Recursively put local dir ./banana to dbfs:/banana
dbfs cp -r ./banana dbfs:/banana

Method3: Using third-party tool named DBFS Explorer
DBFS Explorer was created as a quick way to upload and download files to the Databricks filesystem (DBFS). This will work with both AWS and Azure instances of Databricks. You will need to create a bearer token in the web interface in order to connect.
