On the Bash on Ubuntu on Windows app, I only have
root@localhost:~# ls -a
.bash_history .bashrc .profile
How do I access all of the Windows folders like Documents, Downloads, etc.?
You'll be able to use any Bash commands directly to operate on the files and folders in that Windows directory. By using this method, you don't have to manually
cd into your directories especially when you've a deep-rooted directory to access.
Update as of Windows 10 1809:
Above still works, but there's an easier method now.
