Can't open a .hht file?
When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize a filename extension, you receive the following message:
Windows can't open this file:
example.hht
To open this file, Windows needs to know what program you want to use to open it. Windows can go online to look it up automatically, or you can manually select one from a list of programs that are installed on your computer.
To avoid this error, you need to set the file association correctly.
- Open Control Panel > Control Panel Home > Default Programs > Set Associations.
- Select a file type in the list and click Change Program.
