Can I change the extension of TOP files?

  • Whether the TOP file is damaged.
  • Whether the TOP file is incorrectly linked in the registry entries.
  • Whether the TOP file extension has been accidentally removed from the Windows registry.
  • Whether the installation of an application that supports the TOP file format is incompletely.
