Files not showing up in Notebook's Explorer panel

[BenBlackswan]

In my lakehouse named "SparkSeptember", I have a csv file in the Files folder like this

However, in the Explorer panel of the Notebook, the Files is empty. I have refreshed the page and closed the Notebook and restarted the notebook, but the CSV file still does not show up in Explorer.

you can see that I was able to read it into the dataframe in Notebook

So i'm confused if this is a bug or it suppose not to show up in Explorer?

Hi @BenBlackswan,

You’re seeing the file load successfully in your notebook, but it’s not appearing in the Explorer panel, and that’s expected behavior.

This happens because the Explorer panel only reflects files that are registered or uploaded via the Lakehouse UI, not files added programmatically or through APIs. If you added the file directly (e.g., using code or from an external source), it will be available to read via Spark or DBFS paths like Files/yourfile.csv, but it may not show up in the visual Explorer until explicitly registered.

To view such files:
Click on "Files" in the Notebook.
A panel will open between the Notebook and Data Items pane.
If the file was uploaded via the UI, it will appear there.

Hi @BenBlackswan 

You have to click on Files then your files will be shown next this Data Items Pane(Right side).

Let me explain you. If you see below image, some accpeted csv file is ther in my Lakehouse under files section.

Now when I navigate to my notebook, You have to click on Files(1) then it will open a window(2) in between Data items and Notebook. In that you'll be able to see all our csv file under Files section.

Hope you are clear now.

Thank you!
