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, made an account just to comment!

nice, i didnt know that these scripts exists, now i write a version that copy from the a shared folder, by uid:

function myFunction() {
  const ORIGIN_FOLDER = '<folder id>'
  const DESTIN_FOLDER = '<folder id>'
  const SKIP_FOLDERS_ALREADY_IN_DESTIN = true;
  const USE_MAKE_COPY = false;


  let fo = DriveApp.getFolderById(ORIGIN_FOLDER);
  let fd = DriveApp.getFolderById(DESTIN_FOLDER);
  let rec = (fo,fd)=>{
    let files = fo.getFiles();
    while (files.hasNext()) {
      let sub_fo = files.next();
      const sub_fo_name = sub_fo.getName();
      if (!fd.getFilesByName(sub_fo_name).hasNext()) {
        console.log('coping: '+sub_fo_name);
        if (USE_MAKE_COPY) {
          let newf = sub_fo.makeCopy().moveTo(fd);
          newf.setName(sub_fo_name);
        } else {
          fd.createFile(sub_fo.getBlob()).setName(sub_fo_name);
        }
      } else {
        console.log('file already exists: '+sub_fo_name);
      }
    }
    let folders = fo.getFolders();
    while (folders.hasNext()) {
      let sub_fo = folders.next();
      const sub_fo_name = sub_fo.getName();
      let sub_fd;
      let fd_it = fd.getFoldersByName(sub_fo_name);
      if (!fd_it.hasNext()) {
        console.log('make dir: '+sub_fo_name)
        sub_fd = fd.createFolder(sub_fo_name);
        if (SKIP_FOLDERS_ALREADY_IN_DESTIN) {
         rec(sub_fo, sub_fd);
        }
      } else {
        sub_fd = fd_it.next();
      }
      if (!SKIP_FOLDERS_ALREADY_IN_DESTIN) {
        rec(sub_fo, sub_fd);
      }
    }
  }
  rec(fo, fd);
}

to get folder id open the folder you want and look the url: "https://drive .... folders/<folder-id>"

unfortunaly, makeCopy not work, so i used getBlob, poorly eficient but no hand work needed...
