How to delete all files and folders in one folder on Android

Question

I use this code to delete all files:

File root = new File(\"root path\");
File[] Files = root.listFiles();
if(Files != null) {
    int j;
    for(j = 0; j < F         


        

Answer 1

This code works for me. "imagesFolder" has some files and folders which in turn has files.

  if (imagesFolder.isDirectory())
  {
       String[] children = imagesFolder.list(); //Children=files+folders
       for (int i = 0; i < children.length; i++)
       {
         File file=new File(imagesFolder, children[i]);
         if(file.isDirectory())
         {
          String[] grandChildren = file.list(); //grandChildren=files in a folder
          for (int j = 0; j < grandChildren.length; j++)
          new File(file, grandChildren[j]).delete();
          file.delete();                        //Delete the folder as well
         }
         else
         file.delete();
      }
  }
