: Apps like WhatsApp or Telegram often generate similar strings for media files stored in your "Sent" or "Cache" folders to keep them organized and obfuscated from the main gallery.

: In Windows, ensure "File name extensions" is turned on to verify it is truly a .mp4 and not a hidden .exe (e.g., video.mp4.exe ).
