Answer 1

You have to go though all the folder recursively and find out the files

int mCount;

getTotalFiles(File dir) {
    File[] files = dir.listFiles();
    for (File file : files) {
        if (file.isDirectory()) {
            getTotalFiles(file);
        } else {
            mCount++;
        }
    }
}
