Based on @Mark response I enhanced my knowledge a bit further.
Here is the link to the Visual Studio Code website that explains it in more detail
- Click on the “Explorer” icon in Visual Studio Code.
- Click on the “Explorer” panel background and type what you want to filter.
In my case i typed “.scala” and all other that did not have the scala extension were removed from view.
To remove the filter, simply click the cross next to the red text that represents what you typed as a filter.
The cross appears when you hover your mouse over the text.
