For shits and giggles, I set up a windows 10 vagrant box because I
didn't believe Microsoft would have solved path mapping between Windows
and WSL / ubuntu files.

I get the same errors Satish posted (Satish, as always, you right).

vagrant at win10:~$ cd
vagrant at win10:~$ echo foo >> foo.txt
vagrant at win10:~$ notepad.exe foo.txt # error; can't find file
vagrant at win10:~$ cd /mnt/c
vagrant at win10:/mnt/c$ mkdir foo; cd foo
vagrant at win10:/mnt/c/foo$ echo foo >> foo.txt
vagrant at win10:/mnt/c/foo$ notepad.exe foo.txt # works
vagrant at win10:/mnt/c/foo$ notepad.exe $PWD/foo.txt # error

¯\_(ツ)_/¯
