Remove "Copy of" filename prefix when copying an entire folder from one Google Drive account to another Google Drive account

Drive rename.js

/* Need to copy an entire folder from one Google Drive account to another Google Drive account? 
 * 1. Right-click on original folder in Google Drive
 * 2. Share with the destination Google account
 * 3. Go into destination account's Google Drive
 * 4. Find the shared folder under "Shared with me"
 * 5. Select all the files (Ctrl-A / Cmd-A)
 * 6. Right-click, Make a copy
 * 7. Create a New Folder in destination account's Google Drive
 * 8. Go to Recent
 * 9. Select all recently copied files and move to the new folder
 * 10. Great, except all the filenames begin with "Copy of"xxxxxx.txt
 * 11. Create a new Apps Script, perhaps using Google Sheets, and use the below script to remove the "Copy of" filename prefix!

Thank you. Both all and specific folders script worked for me. Saved me so much time and trouble. This was an awesome find.

TY

Works great! Thank you. I'd love to get a script that will work with subfolders.

function fileRename() { var files = DriveApp.getFiles();

while(files.hasNext()){ var file = files.next() var fileName = file.getName(); if (fileName.indexOf('Copy of ') > -1) { fileName= fileName.split('Copy of ')[1]; file.setName(fileName); }; }; }

This works for every file in your drive. If theres any flaw, someone can point it out..!

Thanks man.
It works (〃￣︶￣)人(￣︶￣〃)

Fantastic, thank you!

Just wanted to leave a huge thank you (!!) for this script! It works flawlessly. I made a Google Apps script inside the drive folder with the files, put in the folder name in this function, adjusted the prefix and it was all solved without any hassle. You cannot imagine how much help this has been.

I keep getting the following error

"Exception: Access denied: DriveApp.
fileRename @ Code.gs:9"

I reworked this a bit to be fully recursive and to include the parent folder ID.

function fileRename() {
  var parentfolder = DriveApp.getFolderById('XXXXXXXXXXXXXXXXXXXXXXX');
  var recursive = true;

  getFilesFromFolder(parentfolder);

  var folders = parentfolder.getFolders();
  while(folders.hasNext() && recursive){
    var folder = folders.next();
    getFilesFromFolder(folder);
  }
}

function getFilesFromFolder(folder){
  var folderName = folder.getName();
  Logger.log(folderName);
  var files = folder.getFiles();
  while(files.hasNext()){
    var file = files.next()
    var fileName = file.getName();
    if (fileName.indexOf('Copy of ') > -1) {
        Logger.log(fileName);
        fileName= fileName.split('Copy of ')[1];
        file.setName(fileName);
    };
  };
}

Thanks, @edoan! -Saved my day!

I'm using the Chinese version, and my original file is named "a.pdf." After making a copy, the file is named "a.pdf 的副本" (a copy of a.pdf). I can quickly change it back to "a.pdf," but when I download it, the default download filename becomes "a.pdf.pdf 的副本.pdf 的副本" (repeated twice). Does the English version have the same issue? I can't find a way to fix the default download filename.

In my comment, the section that rewrites it is this, which should be able to be altered for other languages:

while(files.hasNext()){
    var file = files.next()
    var fileName = file.getName();
    if (fileName.indexOf('Copy of ') > -1) {
        Logger.log(fileName);
        fileName= fileName.split('Copy of ')[1];
        file.setName(fileName);
    };
  };

I can change the name, but when I download it, the default file name is very "ugly". I wonder if I can change the default file name. :(

I asked Google One and they said this problem does not occur in the English version. As for whether it can be solved, I have to report it to google.drive. Thank you all.

That is an excellent script. Below is some updated code you can add to a gsheet script. It adds a menu item to execute the script to the gsheet menu bar and provides a popup box so you can enter the folder name that contains the files with "Copy to " that need to be fixed up.

function onOpen() {
var SS = SpreadsheetApp.getActiveSpreadsheet();
var ui = SpreadsheetApp.getUi();
ui.createMenu('Remove "Copy of" from start of file names in a folder')
.addItem('Start script', 'fileRename')
.addToUi();
};

function fileRename() {
var inputFolder = Browser.inputBox('Enter folder ID', Browser.Buttons.OK_CANCEL);
if (inputFolder === "") {
Browser.msgBox('Remove "Copy of" from the start of file names in this folder:');
return;
}

var folders = DriveApp.getFoldersByName(inputFolder);
var folder = folders.next();
var files = folder.getFiles();
var fileCnt=0;
var renamedCnt = 0;

while(files.hasNext()){
fileCnt++;
var file = files.next()
var fileName = file.getName();
if (fileName.indexOf('Copy of ') > -1) {
fileName= fileName.split('Copy of ')[1];
file.setName(fileName);
renamedCnt++;
};
};
SpreadsheetApp.getUi().alert('Removed "Copy of" from: '+renamedCnt+" Total Files Processed:"+fileCnt);
}

Thank you, it was really useful!
