Delete curent item in a Javascript while hasNext-loop?

I have read 10+ questions about deleting items in Javascripts loops but they don't seem to apply to my situation.
I have this code
var childFolders = parent.getFolders();
// List folders inside the folder
while (childFolders.hasNext()) {
var childFolder = childFolders.next();
//processing childFolder
After this I want to delete the current item (childFolder) from the array childFolders. The reason is that I am doing some work in a Google Apps script but it often takes too long and times out so I need to be able to restart the loop and only have unprocessed items left in the array. To achieve this, in every loop, I copy the content of childFolders into a permanent storage that I can restore on the next run.

I believe your goal is as follows.
You want to stop the loop of the folder iterator, and when you run the script again, you want to start the folder iterator from the stopped iterator.
In this case, how about using "ContinuationToken"? When "ContinuationToken" is used, I thought that your goal might be able to be achieved by the native methods of Google Apps Script. When this is reflected in your script, how about the following script?
Sample script:
Please set var parent = DriveApp.getFolderById("###");.
// When you want to clear the token, please run this function.
function clearToken() {
PropertiesService.getScriptProperties().deleteProperty("token");
}
// This is the main function.
function main() {
var parent = DriveApp.getFolderById("###"); // Please set your parent folder.
var numberOfLoop = 2; // The folder iterator is run every this number.
var p = PropertiesService.getScriptProperties();
var token = p.getProperty("token");
var childFolders = token ? DriveApp.continueFolderIterator(token) : parent.getFolders();
var count = 0;
while (childFolders.hasNext()) {
count++;
var childFolder = childFolders.next();
//processing childFolder
console.log(childFolder.getName()); // This is a sample.
if (count == numberOfLoop) {
var token = childFolders.getContinuationToken();
p.setProperty("token", token);
break;
}
}
}
When you run main function, in this sample script, 2 folders are processed and the script is finished. When you run main again, the folder iterator is started from the continuation.
When you want to start from the 1st folder iterator, please run clearToken.

From your following reply,
It is the script in step 3 here ourtechroom.com/fix/… I have problem with. I changed it to add all files to an array first and insert them into a sheet in a separate step at the end but that wasn't enough. Hence my question.
My issue is that your solution is a little too complicated for me. That is, I have a hard time applying your solution to the script in the link.
Do you want to retrieve the file metadata of all files in your Google Drive? If my understanding is correct, I think that the script in your link is a high process cost because appendRow is used in the loop. Ref I thought that this might be the reason for your actual situation. If my understanding is correct, how about the following sample script?
Usage:
1. Install Google Apps Script library.
You can see how to install Google Apps Script library of [FilesApp] at here.
2. Enable Drive API.
This modified script uses Drive API. So, please enable Drive API at Advanced Google services.
3. Sample script.
Please copy and paste the following script to the script editor of Spreadsheet. And, please set the top folder ID to folderId. If you use var folderId = "root";, all files in your Google Drive are retrieved.
function myFunction() {
var folderId = "###"; // Please set the top folder ID.
var header = ["parent", "folder", "name", "update", "Size", "URL", "ID", "description", "type"]; // This is from your script.
var obj = FilesApp.createTree(folderId, null, "files(name,modifiedTime,size,webViewLink,id,description,mimeType)");
var values = [header, ...obj.files.flatMap(({ folderTreeByName, filesInFolder }) => {
const f = [folderTreeByName.join("|"), folderTreeByName.pop()];
return filesInFolder.length == 0 ? [[...f, ...Array(7).fill(null)]] : filesInFolder.filter(({ mimeType }) => mimeType != MimeType.FOLDER).map(({ name, modifiedTime, size, webViewLink, id, description, mimeType }) => [...f, name || null, new Date(modifiedTime), size || 0, webViewLink, id, description || null, mimeType]);
})];
SpreadsheetApp.getActiveSheet().clear().getRange(1, 1, values.length, values[0].length).setValues(values);
}

How to get Google script trigger to fire automatically (works manually) when creating a new folder

I created a script to create a new folder every time a form is submitted. The point of the script was to put each newly created folder in a specific parent folder determined by a column value on a spreadsheet (new values are generated when forms are submitted). At the moment the script does not fire automatically even though a trigger event is setup, but will fire and create the new folder in the proper location when manually run. Any help would be appreciated.
function createNewFolder() {
// identify the sheet where the data resides
var ss = SpreadsheetApp.getActive();
var names = ss.getSheetByName("Form Responses 1");
var ids = ss.getSheetByName("Form Responses 1");
//identify the cell that will be used to name the folder
var getName = names.getRange(names.getLastRow(), 3).getValue();
//identify the cell that determines which parent folder to use
var folderId = ids.getRange(ids.getLastRow(), 5).getValue();
//identify the parent folder the new folder will be in
var parentFolder = DriveApp.getFolderById(folderId);
//create the new folder
var newFolder = parentFolder.createFolder(getName);
}
The trigger fails about 85% of the time and is setup to fire when a new form response is logged on the associated spreadsheet.

Try replacing your onFormSubmit function with this:
This function should be created in the spreadsheet that has the linked sheets. This function utilizes the data that is sent in the form submit event object. Don't forget to include the 'e' in the function as a parameter.
function createNewFolder(e) {
var parentFolder = DriveApp.getFolderById(e.values[4]);
var newFolder = parentFolder.createFolder(e.values[2]);
}
Event Object Form Submit
Also you may want to look at this question since we have been seeing a lot of problems with spurious form submit triggers. If you don't need to implement it fine but it might be something to consider.

It's most likely an async issue. The parentFolder.createFolder function probably is getting called before the parentFolder is done fetching data from DriveApp.
Try this:
var newFolder = parentFolder.then(() => {
parentFolder.createFolder(getName)
})

How to run a standalone script on multiple google spreadsheets?

I have a standalone script that I need to run on Multiple Google Spreadsheets. I am able to assign a script to 1 spreadsheet using the following code:
function filter() {
var ss = SpreadsheetApp.openById('ID');
How to assign this to multiple spreadsheets?

There are more than a single way to do it.
1) You can manually get the id's of the various spreadsheets and hard code the id's as an array in the stand alone script.
2) You can move all the spreadsheets required to a single folder and automate opening the folder and opening the files in the particular folder. For this, say, the folder containing the required spreadsheets is "All spreadsheets", then try out the following code.
function myfunction()
{
var root = DriveApp.getFoldersByName("All spreadsheets");
while (root.hasNext())
{
var folder = root.next(); //If the folder is available, get files in the folder
var files = folder.getFiles();
while(files.hasNext()) //For each file,
{
var spreadsheet = SpreadsheetApp.open(files.next());
required_function(spreadsheet); //Call the required function
}
}
}
Hope it helps :)

cannot find method copyTo error after creating new file in sheet

Would really appreciate your help here.
I'm creating a two step process where:
1. Create a new file named after a cell from the file to be copied from.
2. Copy the sheet to the newly created file.
I'm doing this because we will be creating unique files for several clients and I'd like to automate it.
Since I'm still new, I've been putting together code from various sources and modifying it to put what I want. However, this code creates a new file perfectly, but refuses to copy the content to the newly created file. I keep on getting a "cannot find method CopyTo error" and despite a ton of research and tweaking, I cannot get it to work. Help!?
function copy2() {
var folder=DriveApp.getFoldersByName("Dummy").next();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0,1];
var cellWithFileName = ss.getRange("A1");
var name = cellWithFileName.getValue();
var file=SpreadsheetApp.create(name);
var fileID = file.getId()
var copyFile=DriveApp.getFileById(fileID);
var destination = DriveApp.getFileById(fileID)
folder.addFile(copyFile);
DriveApp.getRootFolder().removeFile(copyFile);
ss.getSheetByName("Sheet1").copyTo(fileID);
}
Thanks

At copyTo(destination), destination is not file ID. It's Spreadsheet. So how about the following modification?
From :
ss.getSheetByName("Sheet1").copyTo(fileID);
To :
ss.getSheetByName("sheet1").copyTo(file);
Reference :
copyTo(spreadsheet)
If this didn't work, please tell me. I would like to modify.

I need to overwrite an existing Google Sheets file with an attached Script

I have a Google Sheets file with an attached Script. The script does a number of things, one is it makes a clone of it self using makeCopy. This portion works. Now I want to be able to keep the same cloned Google file name and same Google file ID and just update the content which includes a Spreadsheet and the associated Google script.
if (!fileFound){
var file = masterSSFile.makeCopy(reportFileName, RepFolder);
} else {
oldFile.setContent(masterSSFile.getBlob());
}
When I use makeCopy with the same file name it creates a second file with the same name but with a different file ID.
The else portion fails because .setContent argument seems to just accept text. The result is the word "Blob" in the oldFile, everything else is gone.
I have other scripts that update the contents of a existing spreadsheet by overriding the contents of the various sheets, but I also want the associated script to also be included in the updated file keeping the same file ID.

I found this....
Overwrite an Image File with Google Apps Script
and tried using
var masterSpreadsheetID = SpreadsheetApp.getActiveSpreadsheet().getId();
var masterSpreadsheetFile = DriveApp.getFileById(masterSpreadsheetID);
var oldFileID = oldFile.getId();
var oldFileName = oldFile.getName();
var newBlob = masterSpreadsheetFile.getBlob();
var file = {
title: oldFileName,
mimeType: 'application/vnd.google-apps.spreadsheet'
};
var f = Drive.Files.update(file, oldFileID, newBlob);
I get error: "We're sorry, a server error occurred. Please wait a bit and try again. " on this line: "Drive.Files.update(file, oldFileID, newBlob);"
After reading this:
https://github.com/google/google-api-nodejs-client/issues/495
it looks like Drive.Files.update(), does not support bound scripts.
