Example
function processGoogleDriveFiles() {
var arrayAllFileNames,continuationToken,files,filesFromToken,fileIterator,thisFile;//Declare variable names
arrayAllFileNames = [];//Create an empty array and assign it to this variable name
files = DriveApp.getFiles();//Get all files from Google Drive in this account
continuationToken = files.getContinuationToken();//Get the continuation token
Utilities.sleep(18000);//Pause the code for 3 seconds
filesFromToken = DriveApp.continueFileIterator(continuationToken);//Get the original files stored in the token
files = null;//Delete the files that were stored in the original variable, to prove that the continuation token is working
while (filesFromToken.hasNext()) {//If there is a next file, then continue looping
thisFile = filesFromToken.next();//Get the next file
arrayAllFileNames.push(thisFile.getName());//Get the name of the next file
};
Logger.log(arrayAllFileNames);
