Baidu cloud preview is a file stored in Baidu cloud disk, and you can see the contents of the file without downloading. The main reasons why Baidu Cloud cannot be previewed are:

1, preview failed due to poor network speed. Preview the file when the network speed is slow or intermittent, and the previewed file will stay in the preview interface until the network speed becomes better.

2. There are many programs running in the computer, and the preview fails due to the high system load. You can open the Task Manager by pressing CTRL+SHIFT+ESC, and then close some programs that are not commonly used.

3. The previewed file is too large or the format is not supported. If preview is not supported, you can download the file to your computer and then open it.
