Why is Chrome downloading files as .crdownload

The .crdownload file is a temporary file generated when Chrome downloads are not completed and is used to save some downloaded data. Its functions include preventing data loss, improving the efficiency of continuous transmission and ensuring file integrity. If the file has this suffix for a long time, it means that the download may be interrupted or stuck. It is not recommended to open such files because their content is incomplete and forced opening may lead to errors or risks. You can try modifying the suffix or using a recovery tool, but the success rate is limited. Methods to avoid residues include keeping the network stable, waiting for the download to be completed, using professional download tools, and cleaning caches regularly. In short, the .crdownload file is just a temporary state during the download process, and there is no need to worry, but it should not be used directly.

Why does Safari say a plugin is missing?

Safari shows that plugins are missing because the website depends on old plugins such as Flash or Java that are no longer supported. 1.Safari now mainly supports HTML5. In some cases, PDF viewers, Silverlight or Java applets may still be required, but most of these are outdated. 2. The prompt appears usually due to visiting old websites, using old methods to load media or Safari extension settings. 3. Solutions include: refreshing the page, enabling JavaScript, checking website updates, directly opening PDFs with other applications, and using other browsers if necessary. This prompt mostly indicates that the website needs to be updated rather than a browser problem.
