Do you have on where you found this filename, such as a specific website, error message, or folder path?

If you have this file and are trying to find information about its contents:

Many websites automatically rename uploaded video files to a hash (like cc2a71d5... ) to prevent filename conflicts on their servers.

Filenames with long strings of characters after a hyphen are often found in the cache folders of apps like WhatsApp, Telegram, or Discord.

Look at the folder where the file is stored. If it is in a folder like com.apple.MobileSMS or WhatsApp/Media , it is likely a video sent through those services.
