WSL (Windows Subsystem Linux) Folder in Windows
From the Windows side
Use standard Windows networking paths to view your Linux folders using Windows Explorer. In the search box, enter:
\\wsl$
That will bring you to the root directory of your Linux install. To get to your home directory, try something like this, with your version of Linux.
\\wsl$\Ubuntu-18.04\home\
From the Linux side
From Windows terminal or your Linux distribution such as Ubuntu, enter:
explorer.exe .
This will open up Windows Explorer in the folder where you were in Linux.
Use Visual Studio Code if you want an editor that works wonderfully with WSL. Within VSCode, click on the icon on the bottom left corner to connect to your Linux install.
