How to make this google script more efficient - performance

Question

I got this script to get into a folder and get the key for each file.
function listFilesInFolder(id) {
var folder = DriveApp.getFolderById('');
var contents = folder.getFiles();
var file;
var name;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("Imported");
var date;
var size;
sheet.clear();
sheet.appendRow(["Name", "Data", "Size", "Id"]);
while(contents.hasNext()) {
file = contents.next();
name = file.getName();
date = file.getDateCreated()
size = file.getSize()
id = file.getId()
data = [name, date, size, id]
sheet.appendRow(data);
//appendRow
}
};
my problem is that taking too much time to finish going through the whole folder, it usually hits run-time limit before it finishes.
The folder contains 1000+ different files, we automatically upload files daily.
is there any way to make this script more efficient?

Answer 1

I believe your goal as follows.
You want to retrieve the file list just under the specific folder using Google Apps Script.
You want to reduce the process cost of your current script in your question.
Modification points:
In your script, appendRow is used in a loop. In this case, the process cost will be high. Ref
And, I thought that in your situation, when Drive API is used, the process cost might be able to be a bit reduced.
When above points are reflected to your script, it becomes as follows.
Modified script:
Before you use this script, please enable Drive API at Advanced Google services.
function listFilesInFolder(id) {
var folderId = "###"; // Please set the folder ID. If you want to use "id" for this, you can use var folderId = id;
// 1. Retrieve file list using Drive API.
var ar = [["Name", "Data", "Size", "Id"]];
var pageToken = "";
do {
const res = Drive.Files.list({corpora: "allDrives", includeTeamDriveItems: true, supportsAllDrives: true, maxResults: 1000, pageToken: pageToken, q: `'${folderId}' in parents`});
ar = ar.concat(res.items.map(({title, createdDate, fileSize, id}) => [title, createdDate, fileSize || 0, id]));
pageToken = res.nextPageToken;
} while(pageToken);
// 2. Put the file list to Spreadsheet.
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("Imported");
sheet.clear();
sheet.getRange(1, 1, ar.length, ar[0].length).setValues(ar);
}
Note:
From your question, I couldn't understand about the detail of your situation. So in this modified script, the folders in both your Google Drive and the shared Drive can be searched.
