Question

The folder I need to delete is one that is created from my program. The directory is not the same on every pc so the folder code I am using is

userprofile+"\\Downloads\\Software_Tokens"

There will be files in, so I guess i need to recursively delete it. I looked at some samples for that here but it never accepts my path. The path works fine in the code as an environmental variable, because i added code for it

static String userprofile = System.getenv("USERPROFILE");

so can someone just show me the code with my path plugged please?

If you don’t want to use apache library ! You can do it recursively.

  String directory = userprofile + File.separator + "Downloads" + File.separator + "Software_Tokens";
  if (!directory.exists()) {
      System.out.println("Directory does not exist.");
      System.exit(0);
  } else {
      try {
          delete(directory);
      } catch (IOException e) {
          e.printStackTrace();
          System.exit(0);
      }
  }
  System.out.println("Done");
  }
  public static void delete(File file)
   throws IOException {
      if (file.isDirectory()) {
          //directory is empty, then delete it
          if (file.list().length == 0) {
              file.delete();
              System.out.println("Directory is deleted : " + file.getAbsolutePath());
          } else {
              //list all the directory contents
              String files[] = file.list();
              for (String temp: files) {
                  //construct the file structure
                  File fileDelete = new File(file, temp);

                  //recursive delete
                  delete(fileDelete);
              }
              //check the directory again, if empty then delete it
              if (file.list().length == 0) {
                  file.delete();
                  System.out.println("Directory is deleted : " + file.getAbsolutePath());
              }
          }
      } else {
          //if file, then delete it
          file.delete();
          System.out.println("File is deleted : " + file.getAbsolutePath());
      }
