Operations related to buckets or objects

You can use ossbrowser to perform the same bucket-level or object-level operations that you can perform in the OSS console. You can follow the on-screen instructions in ossbrowser to manage buckets and objects.

  • To perform operations related to buckets or objects, you must have the required permissions. For more information, see Permission management.

  • For more information about a specific operation, see the topic related to the operation in the OSS console.




Bucket-related operations

Create a bucket

A bucket is a container used to store objects in OSS. Before you upload an object to OSS, you must create a bucket. For more information about bucket naming rules, regions, access control lists (ACLs), and storage classes, see Create buckets.

Delete a bucket

If you no longer use a bucket, delete the bucket to avoid unnecessary charges. For more information about how to delete a bucket, see Delete buckets.

Object-related operations

Upload an object

By default, ossbrowser uses multipart upload and resumable upload to upload objects. The object to upload cannot exceed 48.8 TB in size. If an upload is interrupted before the upload is complete, the uploaded portion is stored as parts in the bucket. If you no longer need these parts, you can use one of the following methods to delete the parts to avoid additional storage fees.


If the uploaded object has the same name as an existing object in the bucket, the existing object is overwritten.

Download an object

Select the object to download and click Download in the Actions column to download the object.

Preview an object

Click the name of an object to preview the object.

Copy an object

Select the object to copy, click Copy, and in the destination bucket, click Paste.

Move an object

Choose More > Move.


The object that you can move or copy by using ossbrowser cannot exceed 5 GB in size. To move or copy an object that is larger than 5 GB, we recommend that you use ossutil.

Share an object

You can share the URL of an object with third parties. This way, the third parties can download or preview the object. Find the object to share and click Address in the Actions column to generate a URL.
