This topic describes how to manage buckets and objects in ossbrowser 2.0. Operations include creating and deleting buckets, and uploading, downloading, previewing, copying, moving, and sharing objects.
Prerequisites
You have installed and logged on to ossbrowser 2.0. For more information, see Install ossbrowser 2.0 and Log on to ossbrowser 2.0.
Scenarios
Upload and download objects larger than 5 GB.
ossbrowser 2.0 uses multipart upload and resumable upload by default. The maximum object size is 48.8 TB. During the upload process, ossbrowser 2.0 automatically splits the object into parts and merges them after the upload is complete.
ImportantTransferring objects larger than 10 GB over a public network can fail due to network instability. If you are not on an internal network and need to transfer objects larger than 10 GB, use the ossutil 2.0 command line interface.
Access a specific directory in a bucket using an authorization code.
ossbrowser 2.0 supports logon using temporary authorization codes. You can provide these codes to other users to grant them temporary access to a specific directory in your bucket. The authorization code automatically becomes invalid when it expires. For more information, see Object authorization.
Manage buckets
ossbrowser 2.0 supports bucket-level operations that are similar to those in the OSS console. To perform bucket-related operations, follow the instructions in the ossbrowser 2.0 interface.

ossbrowser 2.0 supports object-level operations that are similar to those in the OSS console. To perform object-related operations, follow the instructions in the ossbrowser 2.0 interface. Before you manage objects, click a bucket name to open the object list page.
Due to a policy change to improve compliance and security, starting March 20, 2025, new OSS users must use a custom domain name (CNAME) to perform data API operations on OSS buckets located in Chinese mainland regions. Default public endpoints are restricted for these operations. Refer to the official announcement for a complete list of the affected operations. If you access your data via HTTPS, you must bind a valid SSL Certificate to your custom domain. This is mandatory for OSS Console access, as the console enforces HTTPS.
