A request I got from a member on our forum to write an example to get the total and free diskspace left on the local harddisk. Note: Java SE 1.6 is required to run the sourcecode.

Output:
Java free diskspace demo
c:\ 111,79 Gb total 13,39 Gb left
d:\ 0,00 Gb total 0,00 Gb left
e:\ 0,00 Gb total 0,00 Gb left
f:\ 0,00 Gb total 0,00 Gb left
g:\ 0,00 Gb total 0,00 Gb left
h:\ 0,48 Gb total 0,01 Gb left

PLAIN TEXT
