  • Hi,

    I agree with Rick. The file type here only used for the file to be recognized by the Windows shell in different methods. If we change a file extension, it is similar to change the application we would like to open this kind of file with. 

    And Windows registry is a central hierarchical database used in Windows to store information that is necessary to configure the system for one or more users, applications and hardware devices.

  • Your question is quite vague, but if you change a file extension from .txt to .doc there is nothing going on in the registry.
