ファイルとフォルダにアクセスできるユーザーのリストから人を削除したいとします。すべてのファイルからビューアまたはエディタを削除する方法
私は、以下のコードを使用してこれを行うことができますが、ファイルがたくさんあり、処理を何度か再開し、変数（var count = 5600）を数回手動で変更する必要があります仕事が終わった。
これは適切な解決策ではありませんのでご了承ください。
a）1回の呼び出しですべてのファイル（およびフォルダ）からユーザーを削除できますか？
b）たくさんのファイル/フォルダからビューアを高速に削除するにはどうすればよいですか？
再起動の間にコードを変更しないようにcontinuationtokenを使用することができますが、試していません。
function removeUser()
{
var userName = 'John Doe';
removeUserFromViewersAndEditors_(userName);
};
function removeUserFromViewersAndEditors_(userName)
{ // Remove a user from viewers and editors
// Currently maximum runtime will be exceeded. Using a continuationtoken and automatically starting batches it is possible
// to make it run a sequence of batches and perform its task.
// As this script will not be run often, a manual approach is preferred for now.
// Start with count = 0 and phase = 0
// After the program finishes change phase = 1 and start again
// The program will stop on execution time limit reached change count = ?? based on the log and start again
var count = 5600; // Update if maximum runtime exceeded
var phase = 1; // Update if maximum runtime exceeded
var user = findUser_(userName, phase, count);
var totalRemovedFolders = 0;
var totalRemovedFiles = 0;
if (user != null)
{
if (phase == 0)
{
var countFolders = 0;
var folders = DriveApp.getFolders();
while(folders.hasNext())
{
if (removeUserFromFolderOrFile_(folders.next(), user) == true) totalRemovedFolders++;
countFolders++;

while(count--) files.next(); // Skip a number of files
while(files.hasNext())
