Apps :: Emelfm - free spaceon a drive?

I am trying to sort emelfm out. Is there a way to see the free space available on any of the mounted disks - be they hda or sda in emelfm?

You can use the 'df' button to see the space on all mounted filesystems.

or type on the bottom line:

df -h

that will give you the same read out, but in gigabytes and megabytes. As I understand it -h stands for 'human' (or at least that's how I remember to use it)
