Uploading Files
You can use COSBrowser Mobile Version to upload local and remote files and files from other apps or the file manager to COS and set information such as file storage class, access permission, encryption method, object tags, and metadata during upload.
Uploading image/video
COSBrowser allows you to batch upload images or videos from your album to COS.
Directions
1. On the bucket list or file list page, click + in the top-right corner to display the operation list.
2. In the operation list, click Upload Images.
3. In the file list of the displayed album, select the target files and click Next.
4. (Optional) Configure the upload parameters. COSBrowser allows you to set the following file attributes during upload:
Storage Class: Select the storage class for your object as needed. This field is set to STANDARD by default. For more information, see Overview.
Note:
If your bucket has MAZ configuration enabled, you can only select a MAZ-enabled storage class, such as MAZ_STANDARD. If it also has INTELLIGENT TIERING configuration enabled, you can also select MAZ_INTELLIGENT TIERING.
Access Permissions: select the access permission for your object as needed. This field is set to Inherit by default (inheriting permissions of the bucket). For more information, please see Basic Concepts of Access Control.
Server-Side Encryption: configure server-side encryption for the object you want to upload. COS will automatically encrypt your data as it is written and decrypt it when you access it. Currently, COS offers two encryption types: SSE-KMS (only available in Beijing, Shanghai, and Guangzhou regions) and SSE-COS. For more information, please see Server-side Encryption Overview.
-Object Tag: An object tag is composed of a tag key, equal sign (=), and a tag value, for example, group = IT. You can set, query, and delete tags of a specified object.
Metadata: object metadata, or HTTP header, is a string sent by the server over HTTP before it sends HTML data to the browser. By modifying HTTP headers, you can modify how the webpage responds as well as certain configurations, such as caching time. Modifying an object's HTTP headers does not modify the object itself. For more information, please see Custom Headers.
5. Click Upload.
Uploading file through link
COSBrowser allows you to upload a file through the file link. Every time you enter the app, it will check the current clipboard. If there is any valid file link on the clipboard, a message will pop up asking you whether to upload the file through the link. In this case, you simply need to click Upload Now.
You can also upload a file through the link as follows:

2. Click Upload Link, paste the link for file upload into the text box, select an upload path, and click Upload.
Uploading file shared by third-party app
You can also share a file from another app to COSBrowser to upload it.
Note:
This feature requires that the third-party app supports file sharing to other apps.

Backing up Files
COSBrowser provides the auto backup feature. After this feature is enabled, COSBrowser will automatically back up the files in your album to the specified bucket. To help you manage backup files, COSBrowser displays the backup data as a separate module on the homepage.
Note:
The album backup feature is only supported for the root account.
The album module displays only image and video files. To view all files, go to the bucket list and search for the backup bucket.
Setting backup
Go to Personal > Album Backup and toggle on Automatic Photo Backup or Automatic Video Backup.
Automatic Photo Backup: After it is enabled, all images in the album will be backed up.
Automatic Video Backup: After it is enabled, all videos in the album will be backed up.
Back up over Wi-Fi Only: After it is enabled, files will be backed up only over a Wi-Fi network.
Region: After the backup region is selected, a bucket named from-phone-date-APPID will be created in the region by default.
Note:
The region can be set only before backup is enabled and cannot be modified after the settings are saved.
Enable Smart Storage: This option is suitable for buckets with INTELLIGENT TIERING enabled. After it is enabled, files in the album will be uploaded to COS in INTELLIGENT TIERING. COS will automatically switch between the STANDARD and STANDARD_IA classes based on the access frequency of INTELLIGENT TIERING objects with no data retrieval fees incurred, which reduces your storage costs. For more information, see INTELLIGENT TIERING Overview.

Sharing files
Each file stored in COS can be accessed through a specific URL.

If a file is private-read, you can request a temporary signature to generate a temporary access URL with a certain validity period.
Note:
If you log in with a temporary key, you cannot configure the validity period of the file link, which is 1 hour by default.
If the file is public-read, the URL will not carry a signature and will be valid permanently. If the file is private-read, the URL will carry a temporary signature and will be valid for one hour.
Directions
1. Click a file to enter the File Details page.
The configuration items are described as follows:
Specify Domain: Set the domain name for the URL (optional).
