I've installed the Windows 10 Anniversary Update on my computer.
I would like to know where the /root directory in Bash prompt is within Windows?
I would like to be able to write files in Bash that are accessible from Windows too
i.e.- If I do:
touch /root/foo
Where do I go to access foo in My PC
I believe this link will answer your question:
In short:
%localappdata%\Lxss\rootfs
or
C:\Users\Username\AppData\Local\Lxss\rootfs
The folder changed again:
%localappdata%\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs
C:\Users\{Username}\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs
In my case, running last windows update (creators fall) with ubuntu upgraded, the files are still in C:\Users\Username\AppData\Local\lxss\ but the lxss directory became "invisible". However, just editing the path at the top of the windows explorer manually make it work
Accessing the WSL file-system from within Windows is not supported. As soon as you do anything more than just reading those files from within the Windows environment, things will go wrong.
But the following part of the question is not impossible and easily supported, so I'll answer this:

You can't (should not) access the Linux filesystem from within Windows, but you can quite easily access the Windows file-system from within WSL. You will find all your fixed lettered Windows NTFS drives mounted under /mnt/*, so your "C-Drive" is mounted on /mnt/c, and so on.
For example your Windows home user path will be something like /mnt/c/Users/<usernamehere>
You can mount some filesystems yourself: MSDN Blog
sudo mkdir /mnt/sdcard
sudo mount -t drvfs U: /mnt/sdcard
Note that the actual filesystem is in this case was exFAT, so you just use drvfs as long as Windows can read the actual file system.
