For iOS, you can use the Files app to long-press and share the archive with an unzipping utility. Android users can find dedicated RAR extractors on the Google Play Store.

If the extraction fails, it may be due to a corrupted file from an incomplete download or a filename that is too long for your operating system to handle. What is a RAR File?

Use WinRAR or 7-Zip. Right-click the file and select "Extract Here" or "Extract to Hangman_Vdo_Preview_05" to view the video file.
