List all files and folder in google drive

Question

I\'ve been trying to figure this out for a while now. I hope I can get some guidance on this. The purpose of the following script is to get a full list of folders and files with

Answer 1

Recursion is beneficial in this case. The code below calls the recursive method recurseFolder() which takes a Folder and Array as a parameter. It adds all the files in the folder to a list, then calls itself on any subfolders it finds.

function test(){
  var root = DriveApp.getRootFolder();
  var list = [];

  var list = recurseFolder(root, list);
  Logger.log(JSON.stringify(list));

  //This is just how I am testing the outputed list. You can do what you need.
  var sheet = SpreadsheetApp.getActiveSheet();
  list.forEach(function (row){
   sheet.appendRow(row); 
  });
}

function recurseFolder(folder, list){
  var files = folder.getFiles();  
  var subfolders = folder.getFolders();

  while (files.hasNext()){ //add all the files to our list first.
    var file = files.next();
    var row = [];
    Logger.log("File: " + folder.getName());
    row.push(folder.getName(),file.getName(),file.getId(),file.getUrl(),file.getSize(),file.getDateCreated(),file.getLastUpdated())
    list.push(row);
  }


  while (subfolders.hasNext()){   //Recurse through child folders.
    subfolder = subfolders.next(); 
    Logger.log("Folder: " + subfolder.getName());
    list = recurseFolder(subfolder, list); //Past the original list in so it stays a 2D Array suitible for inserting into a range.
  }

  return list;
}

I'm not sure if the output is formatted how you intended so you might need to play with it a little. Note: It will easily time out if run on a larger Drive.
