Object Storage Service:Get started with ossbrowser 2.0

Last Updated:Dec 23, 2025

ossbrowser 2.0 is a free graphical desktop client for managing Object Storage Service (OSS). It supports Windows, macOS, and Linux operating systems and provides an intuitive graphical user interface (GUI) that lets you efficiently perform various operations, including uploading, downloading, and deleting objects. ossbrowser 2.0 runs locally on your device to ensure smooth performance.

Prerequisites

Manage objects

ossbrowser 2.0 supports standard object operations similar to the OSS console. Click a bucket name to open the object list page.

Operation

Description

Upload an object

ossbrowser 2.0 uses multipart and resumable upload by default. The maximum object size is 48.8 TB. If an upload is interrupted and not resumed, parts remain in the bucket. Delete unneeded parts to avoid storage fees.

Important

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

Upload a directory

Click the Upload button at the top of the page and select Upload Directory from the drop-down list box.

Note

The maximum number of objects in a directory and its subdirectories for a single upload is 100,000. If this limit is exceeded, the error files and folders hit limit=100000 is returned and the upload fails.

Download an object

Select an object and click Download.

Note

To download multiple objects, select them and click Download.

Download a directory

Select a folder and click Download.

List objects

Click the bucket name to list objects.

Preview an object

Click the object name to preview the object. You can preview an object of up to 100 MB in size and edit it.

Note

You can preview and edit most text files online, including .java, .js, .go, .php, .py, .json, .html, .csv, .txt, .xml, and .yml.

Copy an object

Select an object, choose More > Copy To, select the destination, and then click Copy > Confirm Copy.

Important
  • The maximum object size for copying is 5 GB. For objects larger than 5 GB, use ossutil.

  • If the operation is interrupted during a batch copy, the tool cannot resume the task.

Move an object

Select an object, choose More > Move To, select the destination, and then click Move > Confirm Move.

Important

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

  • The maximum object size for moving is 5 GB. For objects larger than 5 GB, use ossutil to copy the object and then delete the source object.

  • If the copy fails during the move process, the source object is not deleted. If the copy succeeds but the deletion of the source object fails (for example, due to insufficient permissions), both the source and destination objects are retained.

  • If the operation is interrupted during a batch move, the tool cannot resume the task.

Rename an object

Select the object, click the image icon, select Rename, enter a name, and click Confirm.

Important

The rename operation copies the source object to the destination and then deletes the source object. Note the following:

  • If the copy fails during the rename process, the source object is not deleted. If the copy succeeds but the deletion of the source object fails (for example, due to insufficient permissions), both the source and destination objects are retained.

  • If the operation is interrupted when you rename a folder, the tool cannot resume the task.

Search for objects

Enter a prefix in the search box to filter objects and folders in the root directory.

Restore an object

Select the object and choose More > Restore.

Delete an object

Select the object and choose More > Delete.

Set a symbolic link

Select the object, click the image icon, and select Set Symbolic Link. In the Set Symbolic Link panel, configure Object to Which Symbolic Link Points (Full Path) and click OK.

Set object metadata

Select the object, click the image icon, and select Set Metadata. In the Set Metadata panel, configure metadata and click OK.

Set the object's ACL

Select the object, click the image icon, and select Set ACL. In the dialog box, select an ACL and click OK.
