Prevent Renaming of Google Forms File Upload - google-apps-script

Question

I have a Google Form that uses the File Upload feature that is mentioned on the below site,
https://sites.google.com/site/scriptsexamples/home/announcements/google-forms-file-upload-feature
I am wondering 2 things:
Is there a way to prevent the renaming of the uploaded file. (IE: original_file_name - Name of Uploader)
Concerning the below quote:
If a respondent decides to upload a file directly from his Drive, a
copy will be made and the form owner will become owner of the copy.
Is it possible to identify the original file and remove it so that it does not junk up the uploaders root Drive folder.
function getCurrentResponses() {
var form = FormApp.openById('formID');
var formResponses = form.getResponses();
var numResponses = formResponses.length;
var lastResponse = formResponses[numResponses - 1];
var lastResponseItem = lastResponse.getItemResponses();
var emailAddress = lastResponseItem[0].getResponse();
Logger.log('emailAddress: ' + emailAddress);
var zone = lastResponseItem[1].getResponse();
Logger.log('zone: ' + zone);
var projectName = lastResponseItem[2].getResponse();
Logger.log('projectName: ' + projectName);
var igeURL = lastResponseItem[3].getResponse();
Logger.log('igeURL: ' + igeURL);
//Creating folder for submitted project
var DriveFolder = DriveApp.getFolderById("destinationFolder");
var folderName = projectName;
//create the folder
var folderpath = DriveFolder.createFolder(folderName).addEditor(emailAddress).getId();
//get the path to the folder
var pathtoemail = "https://drive.google.com/drive/folders/"+folderpath;
var file = DriveApp.getFileById(igeURL);
file.getParents().next().removeFile(file);
DriveApp.getFolderById(folderpath).addFile(file);
var fileName = file.getName();
//Create the message and subject of the email
var message = 'Thank you for submitting. Here is the link to your drive folder. Please use this folder to upload and receive related documentation. ' +pathtoemail ; //a custom message, feel free to change anything inside the quotes
var subject = "Form Related Documentation." ;
//send the email
MailApp.sendEmail(emailAddress, subject, message, {
// cc: 'email#email.com' // optional cc
});

Answer 1

I just wanted to post that I was able to create a work-around for the renaming of the file.
var form = FormApp.openById('formID');
var formResponses = form.getResponses();
var numResponses = formResponses.length;
var lastResponse = formResponses[numResponses - 1];
var lastResponseItem = lastResponse.getItemResponses();
var submittedID = lastResponseItem[3].getResponse();
var file = DriveApp.getFileById(submittedID);
var oldFileName = file.getName();
var indexOldFileName = oldFileName.indexOf("-");
var newFileName = oldFileName.slice(0,indexOldFileName - 1);
var indexOldFileExt = oldFileName.lastIndexOf(".");
var newFileExt = oldFileName.slice(indexOldFileExt);
var modName = newFileName + newFileExt;
file.setName(modName);
As for my second question, I still haven't been able to solve it. I will post if I find a solution.

I change your code a little bit so the name of the file is changed to its ID.
function changenametoid() {
var form = FormApp.openById('formID');
var formResponses = form.getResponses();
var numResponses = formResponses.length;
var lastResponse = formResponses[numResponses - 1];
var lastResponseItem = lastResponse.getItemResponses();
var submittedID = lastResponseItem[0].getResponse();
var file = DriveApp.getFileById(submittedID);
var oldFileName = file.getName();
var indexOldFileName = oldFileName.indexOf("-");
var newFileName = submittedID;
var indexOldFileExt = oldFileName.lastIndexOf(".");
var newFileExt = oldFileName.slice(indexOldFileExt);
var modName = newFileName + newFileExt;
file.setName(modName);
}
