    There are several reasons why you may not be able to do this:

    protected locations, and the many different ways different OS's organize drives. Protected locations are impossible to access without hacking (possible legal issues here) or having all the passwords/access rights. OS files as well as many Virus Protection Software files have vastly restricted access, as well as any files that a certain user wishes to mark as protected.

    I have a method for this, however it will take you a very long time depending on the number of files you have on your disk.

    WARNING: Use with caution

        public static List<File> listFiles(final String path, final boolean recursive) {
            final List<File> files = new ArrayList<File>();
            final File startPath = new File(path);
     
            if (startPath != null && startPath.listFiles() != null) {
                for (final File file : startPath.listFiles()) {
                    if (file.isDirectory() && recursive) {
                        files.addAll(listFiles(file.getAbsolutePath(), recursive));
                    } else if (file.isFile()) {
                        files.add(file);
                    }
                }
            }
     
            return files;
        }

    And to invoke this with your drive root, call it like this.

            final List<File> files = listFiles(File.separator, true);

    // Json

    Mr.Json, thank u for ur help. yet i have some doubts.Is "List<File> listFiles" in 1st line the class name or simply a method ? If it is a method, is it just enough to create an object and pass (File.separator, true) as parameters?

    The first code block is the actual method which will call itself, the second code block is the line of code which will start the process off.
