    Object Storage Service:Common operations for ossbrowser 1.0

    Last Updated:May 27, 2026

    ossbrowser is a graphical tool for managing OSS buckets and objects—create, delete, upload, download, preview, copy, move, and share.

    Prerequisites

    You have installed ossbrowser 1.0 and logged on to ossbrowser 1.0.

    Use cases

    • Upload and download objects larger than 5 GB.

      ossbrowser uses multipart upload and resumable upload by default. Maximum object size: 48.8 TB.

    • Access a specific folder in a bucket by using a temporary token.

      Tokens expire automatically.

    Note

    Operations below use list view. Click the image icon to switch to tile view.

    Manage buckets

    Bucket operations work the same as in the OSS console.

    Note

    Bucket operations require appropriate permissions. Permission management.

    Actions

    Description

    Create a bucket

    A bucket is a container for objects. Create a bucket and configure its name, region, ACL, and storage class before uploading objects. Create a bucket.

    List buckets

    Buckets are listed automatically after you log on.

    Delete a bucket

    Delete unused buckets to avoid charges. Delete a bucket.

    View bucket region

    Click a bucket name to view the region ID in the upper-right corner. For example, oss-cn-hangzhou indicates China (Hangzhou).

    All region ID mappings are in Regions and endpoints.

    Manage objects

    Object operations work the same as in the OSS console. Click a bucket name to open its object list.

    Note

    • Object operations require appropriate permissions. Permission management.

    • Same precautions apply as in the OSS console.

    Actions

    Description

    Upload an object

    ossbrowser uses multipart upload and resumable upload by default (maximum: 48.8 TB). If an upload is interrupted and not resumed, completed parts remain in the bucket. Delete unneeded parts to avoid storage fees.

    Important

    Uploading an object with the same name as an existing object overwrites it.

    Upload a folder

    Click the image.png icon to upload a folder.

    Download an object

    Select an object and click Download in the Actions column.

    Note

    You can also select multiple objects and click Download at the top of the page to download them as a batch.

    Download a folder

    Select a folder and click the image.png icon to download it.

    List objects

    Click a bucket name to list its objects.

    Preview an object

    Click an object name to preview it.

    Copy an object

    In Bucket1, select the object, and click Copy. Then, go to Bucket2 and click Paste.

    Important

    • You can copy objects up to 5 GB. To copy objects larger than 5 GB, we recommend that you use the ossutil 2.0 CLI.

    • Interrupted batch copy tasks cannot be resumed.

    Move an object

    Select an object, and choose More > Move.

    Important

    A move operation copies the source object to the destination and then deletes the source object. Note the following:

    • You can move objects up to 5 GB. To move objects larger than 5 GB, we recommend that you use the ossutil 2.0 CLI to copy the objects and then delete the source objects.

    • If the copy succeeds but the source object deletion fails (for example, due to insufficient permissions), both the source and destination objects are retained.

    • Interrupted batch move tasks cannot be resumed.

    Rename an object

    Select an object, and choose More > Rename.

    Important

    A rename operation copies the object under a new name and then deletes the original object. Note the following:

    • If the copy succeeds but the original object deletion fails (for example, due to insufficient permissions), both the original and renamed objects are retained.

    • Interrupted folder rename tasks cannot be resumed.

    Search for an object

    Enter an object prefix in the search box to find matching objects and folders in the root directory.

    Restore an object

    Select an object, and choose More > Restore.

    Delete an object

    To delete an object, click Delete in its Actions column.

    Set symbolic link

    1. Select an object, and choose More > Configure Symbolic Link.

    2. In the Configure Symbolic Link panel, specify the Symbolic Link File or Folder and click OK.

    Manage object metadata

    1. Select an object, and choose More > HTTP Headers.

    2. In the HTTP Headers dialog box, configure the metadata and click OK.

    Share an object

    Click Obtain URL in the Actions column to share an object URL.

    Set ACL

    1. Select an object, and choose More > ACL.

    2. In the Set ACL dialog box, set the ACL and click OK.
