Answer 1

Here is another way to do it without the need of Drive API. (based on Allan response).

function deleteFile(fileName, folderName) {
  var  myFolder, allFiles, file;
  myFolder = DriveApp.getFoldersByName(folderName).next();

  allFiles = myFolder.getFilesByName(fileName);

  while (allFiles.hasNext()) {
    file = allFiles.next();
    file.getParents().next().removeFile(file);
  }
}
