determining the total no of files in the hard disk

[djshanx]

hello all,

i'm trying to build a desktop search engine using java. i would like to know if there is any way by which i can determine the total number of files in the hard disk. our algorithm doesnt do any indexing as such. each time a search string is entered, the searching of the hard disk is done.

to enable the progress bar, we need to specify the maximum value. to specify this maximum value, i need to determine the total number of files in the hard disk.

hoping to get an early reply.

regards,
djshanx.

There has to be a way to "visit" each file on the disk and allow the increment of a count, using a combination of the FileSystemView and File class. Looks to me that FileSystemView.getFiles() in conjunction with the other disk traversing methods will return a list of files in each directory, which you can dimension and then delete (if you are just counting).

I think something like this would work, however it'd probably be slow.

File root = new File("C:/");

public int countFiles(File file)
{
     File[] files = file.listFiles();
     int count = files.length;
     for(int i=0; i<files.count;i++)
     {
          if (files[i].isDirectory())
               count += countFiles(files[i]);
     }
     return count;
}
