Operations related to buckets and objects

ossbrowser supports the same operations related to buckets and objects as the Object Storage Service (OSS) console. You can follow the instructions of ossbrowser to manage your buckets and objects.

Operation Description
Bucket-related operations
  • Create buckets

    A bucket is a container for objects stored in OSS. Before you upload objects to OSS, you must create a bucket. For more information about how to specify the name, region, access control list (ACL), and storage class of a bucket when you create the bucket, see Create buckets.

  • Delete a bucket

    If you no longer use a bucket, you can delete it to avoid incurring further fees. For more information, see Delete buckets.

Object-related operations ossbrowser supports operations such as upload, download, preview, move, and copy objects as well as generate object URLs. When you use ossbrowser to perform object-related operations, take note of the following items:
  • By default, ossbrowser uses multipart upload and resumable upload to upload objects. The object cannot exceed 48.8 TB in size. If an upload is interrupted before the object is completely uploaded, the uploaded portion is stored as parts in an OSS bucket. To avoid additional storage fees, we recommend that you use the following methods to delete these parts if you no longer need them.
    Notice When the uploaded object has the same name as an existing object in the bucket, the existing object is overwritten.
  • The object that you can move or copy by using ossbrowser cannot exceed 5 GB in size. To move or copy objects that are larger than 5 GB, we recommend that you use ossutil.

For more information about other object-related operations, see OSS Console User Guide.
