Answer 1

Some hints:

1. You can use AsyncTask to do something on a separate thread.
2. Think whether you wil be dealing with files in internal or external storage. If latter, you'll need to specify a permission in your manifest file.

3. A simple way of moving a file to a new location:

   File file = new File(filename);

   boolean success = file.renameTo(new File(newName));
