Thread: recursive search of all local disks

How to search all the local disks and list all the files present in the disk? how to detect the removable disk, so that i can search removable disks also. i will be helpfull if i can get a code snippet. thank u in advance.

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.
