如何使用 GAS 列出主文件夹中的所有文件(或仅某些类型的文件)及其在 Google Drive 中的所有子文件夹? [英] How to list all files (or only certains type of files) inside a main folder and all its subfolders in Google Drive using GAS?

问题描述

是否可以创建一个 Google Apps 脚本来列出:

Is it possible to create a Google Apps Script which would list :

1) 特定主文件夹(及其每个相关子文件夹)内的所有文件名?

例子:

根照片2.jpg

根照片3.jpg

...

根照片20102.jpg

RootPhotos20102.jpg

根照片20102010-023.jpg

RootPhotos20102010-023.jpg

...

2) 与 1) 相同，但只有以.ini"结尾的文件名(例如，我有一些不需要的.picasa.ini"文件在我的在线谷歌驱动器中)?

2) same than with 1) but only filenames finishing by ".ini" (as for instance I have some unwanted ".picasa.ini" files that are inside my online google drive) ?

推荐答案

既然你的驱动器中有(真的)很多文件和文件夹，我想首先要做的是了解所有文件夹和如果您的驱动器中有子文件夹，下面的脚本将在您的电子表格中创建第二张工作表，并显示所有文件夹及其各自的树 + url.

Since it appears you have (really) a lot of files and folders in your drive, I guess the first thing to do would be to know all the folders and subfolders you have in your drive, the script below will create a second sheet in your spreadsheet and show all the folders and their respective trees + urls.

它还以秒为单位显示总执行时间，我不必提醒你这个值不应该超过+-300秒......

It shows also the total execution time in seconds, I don't have to remind you that this value should not exceed +-300 seconds...

所以我建议您尝试一下并在此处报告结果时间，然后我们才能更进一步.

So I suggest you try it and report the resulting time here before we can go further.

function listFolders(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  if(!ss.getSheetByName('Sheet2')){ss.insertSheet(1).setName('Sheet2')};
  var sh = ss.getSheetByName('Sheet2');
  var start = new Date();
  var dateString = Utilities.formatDate(new Date(),Session.getTimeZone(), 'MMM-dd-yyyy');
  var topFolder = DocsList.getRootFolder() ; // start point
  var foldersArray = [];
  foldersArray = getFolders(topFolder.getName().replace('Root','MyDrive'),topFolder,foldersArray);
  foldersArray.unshift(['Folders url','path','# SubFolders']);
  //    Logger.log(foldersArray)
  var l = foldersArray.length
  var duration = (new Date().getTime()-start.getTime())/1000;
  var durationString = Utilities.formatString("%01.1f", duration)
  sh.clear();
  sh.setColumnWidth(2,500);
  sh.getRange(1,1,1,foldersArray[0].length).setBackground('#ffffaa').setBorder(true,true,true,true,true,true).setFontWeight('bold');
  sh.getRange(1,1,l,foldersArray[0].length).setValues(foldersArray).setVerticalAlignment('middle').setWrap(false);  
  sh.getRange(l+1,2,1,foldersArray[0].length-1)
  sh.getRange(l+1,1).setFontColor('grey').setFontSize(9).setVerticalAlignment('middle').setWrap(true).setHorizontalAlignment('center').setValue('execution time: '+durationString+' Seconds');
  sh.setFrozenRows(1);
}

function getFolders(path, container,arrayin) {
  var folders = container.getFolders(0, 500);
  var folderCount = folders.length;
  if(path=='MyDrive'){arrayin.push(['https://drive.google.com/?hl=fr&tab=wo#my-drive',path,folderCount])}
  else{arrayin.push([container.getUrl(),path,folderCount])}

  for (var i=0;i<folders.length;i++) {
    var thisFolder = folders[i].getName();
    var thisPath = path+"/"+thisFolder;
    getFolders(thisPath,folders[i],arrayin)
  }
  return arrayin;
}
