What is an OTRKEY file?

OTRKEY files mostly belong to VLC. OTRKEY files are not media files themselves but act as digital keys used to manage TV recording encryption.
When a TV broadcast is recorded using VideoLAN VLC, an OTRKEY file is created to store the encryption key that is needed to decrypt the recording later.
Key Details summarized by FilExt.com:

TV Recording Key: The file securely locks and later unlocks the recorded TV content.

Software Association: This key file is used by VideoLAN VLC. For more technical details, visit the official VLC webpage.

Alternate Use: Similar encryption practices are used in systems by TVOON to protect TV broadcasts.

FilExt.com tip: Do not attempt to manually open or edit the OTRKEY file; it is automatically processed by the media software during playback.

How do you open OTRKEY files?

You need a suitable software like VLC to open an OTRKEY file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your OTRKEY file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application.
