  File Associations in Windows 8
  File associations are what determine which application opens which file. There are many applications out there and a lot of them are cross compaitable by being able to open different formats.

Windows Reader is the default PDF reader in Windows 8 for example.The Photos application is also set to access various image formats with the Xbox Video application doing likewise for all video formats.
  If you would rather set your own specific file associations, then follow this step by step guide.

  3. Step In this Windows select "Set Your Default Programs". From here you need to locate the application that you are seeking to associate with the file types you wish to alter.
