I don't know exactly if I understand you correctly, but perhaps this one
helps:

public void createSomeFiles( String path ) throws IOException {
    File directory = new File(path);
    if ( !directory.isDirectory() )
        throw new IllegalArgumentException( path +
                " denotes no directory." );

    for ( int i = 0; i < 20; i++ ) {
        StringBuilder fileNameBuilder =
                new StringBuilder( directory.getAbsolutePath() );
        fileNameBuilder.append( File.separator );
        fileNameBuilder.append( "File" );
        fileNameBuilder.append( i );

        File f = new File(fileNameBuilder.toString());
        f.createNewFile();
    }
}

For the existing drive, first you need to know what the existing drives
are.  Use the listRoots() method.

http://java.sun.com/j2se/1.5.0/docs/api/java/io/File.html#listRoots()

You'll have to list all the roots (drive letters), throw away the ones
you don't want, if any (maybe you don't want A: and B:, for example, or
you don't want the CDROM).  Then you'll need to make a new button for
each drive left.

Then when the said button is clicked, you have to switch the window,
frame or whatever, and present the user with a new file listing.  Any
new files go in the current directory, so you'll have to store that for
use as well.

Disclaimer: I haven't tried this yet, or used listRoots().  Read the
docs first, make sure it does what you want.
