Last updated: 2022-04-28 14:49:08

    If you are a first time user of COS, we recommend you first read Bucket Overview, Object Overview, Specifications and Limits, and General.

    COSBrowser is a GUI-enabled tool provided by COS. Available on Windows, macOS, Linux, Android, and iOS, it provides an easier way to view, transfer, and manage COS resources.
    This document uses the Windows version as an example to show you in detail how to create buckets, and upload, download, and share objects.

    Prerequisites

    1. The COS service is activated for your Tencent Cloud account. If not, go to COS console and follow the instructions to activate it.
    2. You should log in to COSBrowser using an API key. First, go to the API Key management page to create one.

    Step 1. Download and install COSBrowser


    System requirements of COSBrowser for Windows: Windows 7 32/64-bit or later or Windows Server 2008 R2 64-bit or later
    You can download COSBrowser for other operating systems in COSBrowser Overview.

    Step 2. Log in to COSBrowser

    Use your API Key to log in to COSBrowser.

    Step 3. Create a bucket

    1. After you log in, click Create bucket in the top-left corner of the COSBrowser.
    2. Enter your bucket information in the pop-up window.
    • Name: A user-defined bucket name, for example, examplebucket
    • Region: Region where the bucket resides. Select the region closest to you. For example, if you are in Shenzhen, you can select the Guangzhou region, i.e., ap-guangzhou.
    • ACL: Access permission for the bucket. For example, you can select Private (read-write).
    1. Click OK.

    Step 4. Upload an object

    1. Click the bucket created in Step 3 to go to the bucket management page.
    2. Click Upload > Select Files and select a local file to upload to the bucket, for example, exampleobjext.txt.
    3. Click Upload.

    Step 5. Download an object

    Option 1

    1. Click in the upper-right of the COSBrowser page to switch to list view (Skip this step if you are already in list view).
    2. Under Operation on the right side, click to download the file.

    Option 2

    1. Right-click a file, and in the drop-down list, click Advanced Download.
    2. In the pop-up window, select Rename, Replace, or Skip as needed.
    3. Click Download now. COSBrowser will start downloading the selected file.

    Step 6. Share an object

    Each file stored in COS can be accessed through a specific link. If a file is private-read, you can request a temporary signature to generate a temporary access link with a certain validity period. The two methods for generating object links are as follows:

    Option 1

    1. Click in the upper-right of the COSBrowser page to switch to list view (Skip this step if you are already in list view).
    2. In the action bar to the right of the file, click .
    3. Your link is generated and copied successfully if COSBrowser displays Temporary object url copy success, link effective for 2 hours at the top.
    4. You can now access your file via this link. File links generated in this way are valid for 2 hours. To customize the validity period, you can use option 2.

    Option 2

    1. Click in the upper-right of the COSBrowser page to switch to list view (Skip this step if you are already in list view).
    2. In the Operation column of the target file, click .... In the drop-down list, click Share.
    3. In the Copy URL pop-up window, configure your file URL. If your file is Private read-write, select Signed URL, with validity. Note that the URL is valid for the period of time you specify.
    4. Click Copy to copy the temporary file URL, with which you can access your file.
