Can you rename files in Google Cloud Storage?

I am letting users upload photos, but I want to give them the ability to edit the photo, at least by changing the name they uploaded it with. I am using Javascript through Node.js.

Thanks!

• 1 Which API are you using? You'll want to do a copy followed by a delete. – jterrace Commented Jul 17, 2014 at 20:37
• i'm using cloud-storage and gcloud, neither of which support copying or moving files – user3826544 Commented Jul 18, 2014 at 14:36

This mand:

gsutil mv gs://my_bucket/olddir gs://my_bucket/newdir

will do the job. If you have a large number of files you need to do a multi-processing move, so use this mand:

gsutil -m mv gs://my_bucket/olddir gs://my_bucket/newdir

You can find this information in the docs.

You can rename a file using the storage.move() method.

const {Storage} = require('@google-cloud/storage');
const storage = new Storage();

const oldFileName = 'path/to/old_file.jpg';
const newFileName = 'path/to/new_file.jpg';

storage
  .bucket(bucketName)
  .file(oldFileName)
  .move(newFileName)
  .then(() => {
    console.log(`File ${oldFileName} was renamed to ${newFileName}.`);
  })
  .catch(err => {
    console.error('Error renaming file:', err);
  });

bucketName is the name of the bucket where the file is located.

oldFileName is the current name of the file.

newFileName is the new name that you want to give the file.

You should have the proper permissions.

Yes. You copy it to a new name with the mv mand. Below renames file.html to file.

gsutil mv gs://xxxx/folder/file.html gs://xxxx/folder/file

For more information see Google's gsutil documentation at mv - Move/rename objects.

Here is Python function performs a multi-threaded/multi-processing move:

from subprocess import call, CalledProcessError

def rename_object(self, old_dir, new_dir):
    base_cmd = ["gsutil", "-m", "mv"]
    old_path = "gs://{}".format(old_dir)
    new_path = "gs://{}".format(new_dir)
    cmd = base_cmd + [old_path, new_path]
    try:
        call(cmd)
    except CalledProcessError as e:
        print e
