Common operations in ossbrowser 2.0 - Object Storage Service

This topic describes how to manage buckets and objects in ossbrowser 2.0, including creating, deleting, uploading, downloading, previewing, copying, moving, and sharing.

Prerequisites

Install and log on to ossbrowser 2.0. For more information, see Install ossbrowser 2.0. and Log on to ossbrowser 2.0.

Use cases

Upload and download objects larger than 5 GB.
ossbrowser 2.0 uses multipart and resumable upload by default. The maximum object size is 48.8 TB. It splits the object into parts and merges them upon completion.
Important
Unstable networks may cause failures when transferring objects larger than 10 GB over the Internet. If you are not connected to an internal network and need to transfer objects larger than 10 GB, use the command-line tool ossutil 2.0.
Access specific directories using authorization codes.
ossbrowser 2.0 supports login via temporary authorization codes. Share these codes to grant restricted access to specific bucket directories. The authorization code automatically becomes invalid after it expires. For more information, see Object authorization.

Manage buckets

ossbrowser 2.0 supports standard bucket operations similar to the OSS console.

Operation	Description
Create a bucket	Buckets are containers for objects. Create a bucket before uploading objects. For more information about bucket naming, regions, ACLs, and storage classes, see Create buckets. Click Create Bucket at the top of the page.
List buckets	After you log on to ossbrowser 2.0, the buckets are automatically listed.
Delete a bucket	Delete unneeded buckets to avoid fees. For more information, see Delete buckets. Select the bucket, click the icon, and then choose Delete > Confirm to delete the bucket.
Favorite a bucket	Select the bucket and click the icon to add it to your favorites.
View basic bucket information	Select the bucket and click the icon to view basic information, such as region, ACL, and creation time.

Manage objects

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. Manually delete parts: Click Parts, select the parts, and click Delete Selected. Automatically delete parts: For more information about how to configure lifecycle rules, see Lifecycle rules based on the last modified time. 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 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 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 icon, and select Set Metadata. In the Set Metadata panel, configure metadata and click OK.
Share an object	Share object URLs with third parties for downloading or previewing. Select the object, click the icon, and select Obtain URL. Set a validity period, click Generate, and copy the URL.
Set the object's ACL	Select the object, click the icon, and select Set ACL. In the dialog box, select an ACL and click OK.
