Question

I would like to write a google apps script to trash every empty folder into my google drive, which method / property should I use to examine the current folder (I can write a cycle) is really empty, id est without any file or any other nested folder inside?

And, what happens if you trash a folder which has some files linked to? Do those files get trashed to or do they get orphaned (if linked to just on folder, of course)?

Thank you.

This is what I coded after the first useful answer, I just inserted pagination:

function FindEmptyFolders() {

var pageSize = 200;
var folders = null;
var token = null;
var i = null;

Logger.clear()

do {
var result = DocsList.getAllFoldersForPaging(pageSize, token);
folders = result.getFolders();
token = result.getToken();
  for (var i = 0; i < folders.length; i++) {
      for(n=0;n<folders.length;++n){
        if(folders[n].getFiles().length==0 && folders[n].getFolders().length==0){
            folders[n].setTrashed(true)
            Logger.log(folders[n].getName())
            Logger.log(folders[n].getUrl())
        }
      }    
  } 
 } while (folders.length == pageSize);

  MailApp.sendEmail('[e-mail]', 'Script eliminazione folders vuoti Log', Logger.getLog());

} 

Answer 1

this code does the job

function testForEmptyFolders() {
var folders = DocsList.getAllFolders()
  for(n=0;n<folders.length;++n){
    if(folders[n].getFiles().length==0 && folders[n].getFolders().length==0){
     folders[n].setTrashed(true)
     Logger.log(folders[n].getName())
     }
   }
}

The logger shows the names of the deleted folders
