在 Google Apps 脚本中，我将如何获取所有子文件夹和所有子子文件夹以及所有子子文件夹等？

Question

我正在尝试重命名指定文件夹中的每个文件以及所有子文件夹中的所有文件，但我不知道该怎么做。到目前为止，我有这个脚本可以重命名给定 ID 的文件夹中的每个文件，但我需要执行所有子文件夹。

function renameFilesInFolder(folderID) {
  var folder = DriveApp.getFolderById(folderID)
  var files = folder.getFiles(),
      fileNames = []
  

  while(files.hasNext()){
    var file = files.next()
    var oldFileName = file.getName()
    var checkIfMatch = oldFileName.substring(oldFileName.length - 3);
    var newFileName = ""
    if (checkIfMatch=="OBS"){
      newFileName = oldFileName
    } else {
      newFileName =oldFileName+"_OBS"
    }
    file.setName(newFileName)
    Logger.log(newFileName)
  }
}

谢谢！

这将通过将它们写入电子表格的文件夹进行递归。

var level=0;
function getFnF(folder) {
  var folder= folder || DriveApp.getRootFolder();
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('FilesAndFolders')
  var files=folder.getFiles();
  while(files.hasNext()) {
    var file=files.next();
    var firg=sh.getRange(sh.getLastRow() + 1,level + 1);
    firg.setValue(Utilities.formatString('File: %s', file.getName()));
  }
  var subfolders=folder.getFolders() 
  while(subfolders.hasNext()) {
    var subfolder=subfolders.next();
    var forg=sh.getRange(sh.getLastRow() + 1,level + 1);
    forg.setValue(Utilities.formatString('Fldr: %s', subfolder.getName()));
    level++;
    getFnF(subfolder);
  }
  level--;
}

这样会快一点

function getFnF1(folder = DriveApp.getRootFolder()) {
  let tree = JSON.parse(PropertiesService.getScriptProperties().getProperty('FnF'));
  //Logger.log(JSON.stringify(tree));
  if (tree.level < level) {
    tree.level = level;
    PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  }
  const files = folder.getFiles();
  let row = Array.from([...Array(level).keys()], ((x, i) => { if (i == level - 1) { x = folder.getName(); } else { x = ''; } return x; }));
  tree.txt.push(row);
  row = Array.from([...Array(level).keys()], ((x, i) => { if (i == level - 1) { x = 'bold'; } else { x = 'normal'; } return x; }));
  tree.fwt.push(row);
  PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  if (files.hasNext()) {
    let row = Array.from([...Array(level).keys()], ((x, i) => { if (i == level - 1) { x = 'Files:'; } else { x = ''; } return x; }));
    tree.txt.push(row);
    tree.fwt.push(['normal']);
    PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  }
  while (files.hasNext()) {
    let file = files.next();
    let row = Array.from([...Array(level + 1).keys()], ((x, i) => { if (i == level) { x = file.getName(); } else { x = ''; } return x; }));
    tree.txt.push(row);
    tree.fwt.push(['normal']);
    PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  }
  const subfolders = folder.getFolders()
  while (subfolders.hasNext()) {
    let subfolder = subfolders.next();
    level++;
    getFnF1(subfolder);
  }
  level--;
}

function getFilesAndFolders1() {
  const fldr = DriveApp.getFolderById(gobj.globals.projectsfolderid);
  const ss = SpreadsheetApp.getActive();
  ss.toast("Entry");
  const sh = ss.getSheetByName('Sheet1');
  sh.clearContents();
  SpreadsheetApp.flush();
  PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify({ txt: [], fwt: [], level: 0 }));
  getFnF1(fldr);
  //Logger.log(PropertiesService.getScriptProperties().getProperty('FnF'));
  let tree = JSON.parse(PropertiesService.getScriptProperties().getProperty('FnF'));
  const l = tree.level + 1
  tree.txt.forEach(r => {
    if (r.length < l) {
      //Array.from(Array(l - r.length).keys()).forEach(e => r.push(''));
      r.splice(r.length,0,...Array(l-r.length).fill(''));
    }
  });
  tree.fwt.forEach(r => {
    if (r.length < l) {
      //Array.from(Array(l - r.length).keys()).forEach(e => r.push('normal'));
      r.splice(r.length,0,...Array(l-r.length).fill('normal'));
    }
  });
  //Logger.log(JSON.stringify(tree));
  sh.getRange(1, 1, tree.txt.length, tree.level + 1).setValues(tree.txt);
  sh.getRange(1, 1, tree.fwt.length, tree.level + 1).setFontWeights(tree.fwt);
  PropertiesService.getScriptProperties().deleteProperty('FnF');
  ss.toast("EOF");
}
