How to mount and unmount on WSL

Any drive of any filesystem that is already mounted under Windows can be then mounted under WSL. What makes this possible is a filesystem plugin in WSL named DrvFS.

• The C: drive is mounted by default under WSL at /mnt/c.

• To mount a different drive under WSL, create a directory under /mnt and mount using the DrvFS plugin using this syntax:

$ sudo mkdir /mnt/k
$ sudo mount -t drvfs K: /mnt/k

• You can see the list of mounted drives and their mount options using:

$ cat /etc/mtab

• To unmount a mounted drive:

$ sudo umount /mnt/k
