How to check amt of SPACE FREE on HDD

[RichardJ]

New to python, but have all the O'Reilly Python books and was not able to
find the call you would use to check the amount of space is available on a
hard-drive.

The application will be downloading huge amount of data using ftp, so needs
to check how much space is available. At the moment running on WinXP Pro,
but likely to run on Linux.

Very much appreciate any help.
Thanks,
Richard
