Small module that can read the total amount of Disc Space, Used Disc Space and Space left. The administrator configures what to show: a label and unit measure (bytes, Kb, Mb, Gb, Tb).

Notes:
- This module only works on Linux servers, not on Windows IIS!
- On some shared hosting it might show the total shared hosting server space instead of the user's disc space!
- This module won't work if Open basedir protection is ON (in the administrator back-end > System > System Info > Relevant PHP Settings: Open basedir is configured something other than "none").
