Is there any function to see how much space is left on a device (such
as a usb key)? I'm trying to fill in an mp3 reader in a little script,
and this information could be very useful! Thanks!

On windows with the win32 extensions, you might try this:

# Get hard drive info from Windows.
drive = win32api.GetDiskFreeSpace('c:')
print drive[0], "sectors per cluster."
print drive[1], "bytes per sector."
print drive[2], "free clusters."
print drive[3], "total clusters."

You could use wmi to discover where the device has been mounted:
for item in c.Win32_DiskDrive():
print item

instance of Win32_DiskDrive
