Ex. someone submitting the form with a file upload and on form submit it creates a custom folder based on their form response (their name) on Google Drive with their submission in it.

Using this script, I can put all files into one folder, but I don't know enough about script to know where to change what the folder is named

const PARENT_FOLDER_ID = "<<Folder ID here>>";

const initialize = () => {
  const form = FormApp.getActiveForm();

const onFormSubmit = ({ response } = {}) => {
  try {
    // Get a list of all files uploaded with the response
    const files = response
      // We are only interested in File Upload type of questions
        (itemResponse) =>
          itemResponse.getItem().getType().toString() === "FILE_UPLOAD"
      .map((itemResponse) => itemResponse.getResponse())
      // The response includes the file ids in an array that we can flatten
      .reduce((a, b) => [...a, ...b], []);

    if (files.length > 0) {
      // Each form response has a unique Id
      const subfolderName = response.getId();
      const parentFolder = DriveApp.getFolderById(PARENT_FOLDER_ID);
      const subfolder = parentFolder.createFolder(subfolderName);
      files.forEach((fileId) => {
        // Move each file into the custom folder
  } catch (f) {

You are using (verbatim) the script from the article by Digital Inspiration called How to Move Files Uploads from Google Forms to a Specific Folder in Google Drive. The nature of your question suggests that you have little or no experience with Apps Script; if this is so, then I suggest that you begin by reading developers.google.com/apps-script/guides/sheets.

Regarding your question, there are two instructions relating to assigning the folder into which uploads will be saved:

  • Create Parent Folder: To get started, go to your Google Drive and create a new folder (or use an existing folder). Open the folder and grab the ID of the folder from the browser’s address bar as shown in the screenshot.
  • Remember to replace the Folder Id in line #1 with the Id of the folder that you’ve created in the previous step.

Uploads for each unique response are saved to a custom folder within the parent folder. To quote the article: The name of the custom folder is the unique Response Id that Google Forms automatically assigns to every form submission.
