Last updated: 2020-07-06 10:59:12

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

    COSBrowser is a visual interface tool launched by Tencent Cloud. It comes with multiple versions for Windows, macOS, Linux, Android and iOS, allowing for a simpler easier way to view, transfer, and manage COS resources.
    This document will use 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 enabled for your Tencent Cloud account. If not, please go to the COS Console and follow the instructions to activate it.
    2. You login to COSBrowser using an API key. First, go to the API Key management page to create one.

    Step 1. Download and install COSBrowser

    The COSBrowser Windows version can run on Windows 7 32/64-bit or above, and Windows Server 2008 R2 64 or above. To download other versions, go to COSBrowser Overview.


    Step 2. Login to COSBrowser

    Use your API Key to login to COSBrowser.

    Step 3. Creating a bucket

    1. Click Add Bucket in the top left.
    2. Enter your bucket information in the pop-up window.
      • Name: bucket name, such as examplebucket.
      • Region: region where the bucket resides. Please select the region closest to you. For example, if you are in Shenzhen, you can select the Guangzhou region.
      • Access Permission: bucket access permission. For example, you can select "private read/write".
    3. Click OK.

    Step 4. Upload an object

    1. Click the bucket created in Step 3 to enter the bucket management page.
    2. Click Upload > Select files and select a file to upload to the bucket, such as exampleobjext.txt.
    3. Click Upload.

    Step 5. Download an object

    Method 1

    1. Click in the top right of the COSBrowser page to switch to list view (This step can be skipped if you are already in list view).
    2. Under “Action” on the right side, click to download the file.

    Method 2

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

    Step 6. Sharing 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:

    Method 1

    1. Click in the top right of the COSBrowser page to switch to list view (This step can be skipped 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 Method 2.

    Method 2

    1. Click in the top right of the COSBrowser page to switch to list view (This step can be skipped if you are already in list view).
    2. Under Actions on the right side, click ..., and in the drop-down list, click Share.
    3. In the “Copy link with expires” pop-up window, configure your file link. If your file is private read/write, select Copy url with signature…. Note that the link is valid for the period of time that you specify.
    4. Click Copy to copy the temporary file link, with which you can now access your file.
