List all files id inside a folder (no subfolders)

Question

How can I list in a spreadsheet all files id that are located inside a folder ? I have the folder id and the folder contains less than 100 files in total.

function list_all_files_inside_one_folder_without_subfolders(){
var sh = SpreadsheetApp.getActiveSheet();
var folder = DriveApp.getFolderById('0sdfsfd......sfdsdfTg'); // I change the folder ID  here 
// Logger.log('Folder name: ' + folder.getFiles());
sh.getRange(1,1,1,1).setValues('fileID');
}

Thanks

This is quite simple if you read the documentation about how to write in a spreadsheet and how to get Drive's content.

Here is an example you can customize if you want :

function list_all_files_inside_one_folder_without_subfolders(){
  var sh = SpreadsheetApp.getActiveSheet();
  var folder = DriveApp.getFolderById('0B3qSFd3iikE3TERRSHExa29SU3M'); // I change the folder ID  here 
  var list = [];
  list.push(['Name','ID','Size']);
  var files = folder.getFiles();
  while (files.hasNext()){
    file = files.next();
    var row = []
    row.push(file.getName(),file.getId(),file.getSize())
    list.push(row);
  }
   sh.getRange(1,1,list.length,list[0].length).setValues(list);
}
