This code will help you with your current problem:
function myFunction() {
var folderId = "main-id-folder";
// Take the mainder folder
var mainFolder = DriveApp.getFolderById(folderId);
// Take the subfolders inside your main folder
var subFolders = mainFolder.getFolders();
var result = [];
// Iterate over each subfolder
while(subFolders.hasNext()){
var subFolder = subFolders.next();
// Take the files inside the current subfolder
var files = subFolder.getFiles();
// Take each file inside the current subfolder
while(files.hasNext()){
var file = files.next();
var tmp = {
file_name: file.getName(),
url: "https://docs.google.com/spreadsheets/d/" + file.getId() + "/edit#gid=0"
};
// For the current file, stablish the permissions you want
file.setSharing(DriveApp.Access.ANYONE_WITH_LINK, DriveApp.Permission.VIEW);
result.push(tmp);
}
}
Logger.log(result);
}
The problem you had is you were only trying to get the files from your main folder but in order to get the files inside each subfolder, you needed to first take each subfolder using .getFolders(); and then for each one of them, you could use .getFiles();.
