How to open Ubuntu files in an interface friendly editor from Windows?

Absolutely. In Windows VSCode, install either:

• The "Remote - WSL" extension
• The "Remote Development" extension pack, which includes the "Remote - WSL" extension, along with similar features for Docker and SSH.

Once you've installed that, from inside your Ubuntu instance, you can:

code .

... to open the current directory in VSCode. Or:

code filename

to open a particular file.

You can also start from inside VSCode, and open any of your WSL instances to browse the directory structure. You'll find an icon for this that looks like "><" stacked together at the bottom left of the status-bar. That's the "Open a Remote Window" tool.

Alternatively, Ctrl+Shift+P and type "remote" to get a list of the features available from those extensions.

This extension creates a server running inside Ubuntu with which VSCode communicates. It not only allows editing, but also connecting to debuggers in Ubuntu, etc.
