How to solve the problem that WeChat can't open the file preview?

I'm afraid I can't retrieve the failed file. The root of the problem is that you use the garbage cleaning software, which will delete the files cached by WeChat, and then there will be a problem that you can't open them.

So you can only try to avoid cleaning up the garbage frequently, or configure the directory of WeChat without cleaning up, which should avoid your problems.

Your file doesn't seem to be lost, but there is no associated app to open. If you know what format the file is, you can download the corresponding app, such as downloading wps or Office by doc. If it is because of the file suffix, you can find the file in the file manager and rename the file suffix.
