An external viewer refers to a software application or programme that is used to open, display, or interact with files or content from an external source or location. It is typically employed when the native application or software on a system might not support or adequately handle certain file formats or content types.
Examples of external viewers include:
- PDF viewers like Adobe Reader or Foxit Reader, used to open and read PDF documents.
- Media players (such as VLC Media Player) that serve as external viewers for various audio and video file formats.
- Image viewers like IrfanView or XnView, offering enhanced functionalities for image formats.
