7. Preview a file

COSBrowser supports previewing media files, currently including images, videos, and audio. You can click a file name, and enter the file details page to see the preview area above the details.

Note：

• Preview is available for images in most formats, .mp4 and .webm videos, and .mp3. and .wav audios.

8. Generate a file link

Each file stored in COS can be accessed through a specific link. File links with a specified domain such as a CDN acceleration domain name can be generated. If a file is private-read, you can request a temporary signature to generate a temporary access link with a certain validity period.

You can generate file links in the following ways:

• Click Operation on the right of the file and select Copy Link to generate a link and copy it. If the file is public-read, the link will not carry a signature and will be valid permanently. If the file is private-read, the link will carry a signature and be valid for 1 hour.
• In the file details, you can easily generate a link by changing the validity period and tapping Generate a Link.

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.
