Size of free space root disk

Question

Hi
I try to obtain the free space disk of c:\ (under windows NT). I use the class File but i obtain a size of 0 for the drive C:\
I use :
private static boolean estSuperieurAuSeuil(String disque, long seuil) {
File lecteur = new File("c:\");
//File lecteur = new File(disque);
long volumeOccupe = lecteur.length();
     if (volumeOccupe >seuil) {
     return true;
     } else {
     return false;
but volumeOccupe is always equals to 0
Anyone can help me !
Thanks
}

Why don't you implement your own code to calculate the full size of the disk?
Windows system itself does a recursive count.
(Which makes the request for a bug not founded since everytime you ask for the size, you would have to wait until the count is done.)
you could do this :
public long diskSize(File root) {
if(root != null && root.isDirectory()) {
File[] fs = root.listFiles();
long ret = 0;
for(int i = 0; i < fs.length; i++) {
ret += diskSize(fs);
} else {
return root.getSize();
and then call it with diskSize("c:\");
Hopes this helps
