How to programmatically move, copy and delete file

Question

I want to programmatically move, copy and delete files and directories on SD card. I've done a Google search but couldn't find anything useful.

Answer 1

To move a file this api can be used but you need atleat 26 as api level -

move file

But if you want to move directory no support is there so this native code can be used

    import org.apache.commons.io.FileUtils;

    import java.io.IOException;
    import java.io.File;

    public class FileModule {

    public void moveDirectory(String src, String des) {
    File srcDir = new File(src);
    File destDir = new File(des);
     try {
        FileUtils.moveDirectory(srcDir,destDir);
    } catch (Exception e) {
      Log.e("Exception" , e.toString());
      }
    }

    public void deleteDirectory(String dir) {
      File delDir = new File(dir);
      try {
        FileUtils.deleteDirectory(delDir);
       } catch (IOException e) {
      Log.e("Exception" , e.toString());
      }
     }
    }
