ossbrowser is a graphical management tool that is provided by Alibaba Cloud to help you easily manage buckets and objects in Object Storage Service (OSS). For example, you can use ossbrowser to create buckets, delete buckets, upload objects, download objects, preview objects, copy objects, move objects, and share objects.
Video tutorial
Watch the following tutorial video to learn how to quickly get started with ossbrowser.
Prerequisites
ossbrowser is installed, and you have logged on to ossbrowser. For more information, see Install and log on to ossbrowser.
Scenarios
Upload and download a large object that is greater than 5 GB in size.
By default, ossbrowser uses multipart upload and resumable upload to upload an object. The object that you want to upload cannot exceed 48.8 TB in size. ossbrowser automatically splits the object into parts during the upload and combines the parts into a complete object after the parts are uploaded.
Access a directory in a bucket by using a token
You can use a token that is obtained from Security Token Service (STS) to log on to ossbrowser. Tokens can be provided for other authorized users for temporary access to a directory in your bucket. The token automatically becomes invalid after it expires.

Manage buckets
You can use ossbrowser to perform the same bucket-level operations that you can perform in the OSS console. You can follow the on-screen instructions in ossbrowser to manage buckets.
To manage buckets, you must have the required permissions. For more information, see Manage permissions.
Operation | Description |
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 a bucket. |
List buckets | After you log on to ossbrowser, buckets in the Alibaba Cloud account are automatically listed. |
Delete a bucket | If you no longer use a bucket, delete the bucket to prevent unnecessary charges. For more information, see Delete buckets. |
Query the region of a bucket | Click the name of a bucket and view its region in the upper-right corner of the page that appears. For example, oss-cn-hangzhou represents the China (Hangzhou) region. For more information about the mappings between region IDs and region names, see Regions and endpoints. |
Manage objects
You can use ossbrowser to perform the same object-level operations that you can perform in the OSS console. You can follow the on-screen instructions in ossbrowser to manage objects. Before you can manage objects in a bucket, you must click the name of the bucket to view the object list.
To perform a specific operation on objects, you must have the required permissions. For more information, see Manage permissions.
For more information about a specific operation, see the topic related to the operation in the OSS console.
Operation | Description |
Upload an object | By default, ossbrowser uses multipart upload and resumable upload to upload an object. The object that you want to upload cannot exceed 48.8 TB in size. If an upload task is interrupted before the upload task 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.
Important If the uploaded object has the same name as an existing object in the bucket, the existing object is overwritten. |
