Hi,
I cant reproduce the JFileChooser performance in directory listing.

When i retrieve the list of files inside a directory i need to know if
a file is a directory or not, to visualize it as a folder or not, for
instance. I know only this way in java:

File file = new File("z:/");
File[] files = file.listFiles();
for (int i = 0; i < 0; i++)
{
    if (files[i].isDirectory())
    {
        [...]
    } else {
        [...]
    }
}

The problem is that if the original directory is a mounted drive, the
thing can require ages to be accomplished.
In JFileChooser it doesn't take ages at all, it's instantaneous.

Was JFileChooser implemented using java or native code? Is there a way
to replace its perfomance in file listing with plain java?
I tried with a FileFilter, but it didn't solve anything to me.
Thanks
