Answer 1

maybe this?

File root = new File(Environment
              .getExternalStorageDirectory()+"/myPrivateFolder");
if(!root.exists()){
        root.mkdir();
}
else{
    File[] files = root.listFiles(); //access your files
}
File myFile = new File(Environment
              .getExternalStorageDirectory()+"/myPrivateFolder/myFile.txt");
myFile.createNewFile();  // creating file

don ever hardcoe "/sdcard" or smth like this. for more convenient method of navigation each File has methods for accessing abosulutePath, getting info about is file or folder or even exists and other
