What is an ht file?
.ht is the file extension used for HyperTerminal session files. These files store your connection and terminal emulator settings as well as any Key Macros or file transfer settings you have set up.
The ht file is created automatically when you set up a connection in HyperTerminal. By default it is saved into the “HyperTerminal Connections” folder in your start menu under Start->All Programs->HyperTerminal Private Edition->HyperTerminal Connections. You can also open your session files by clicking File->Open in HyperTerminal and selecting the file you want to open.
If you would like to create a desktop shortcut to open your session file directly click File->Open, then right click on the session file, and select Send To->Desktop.
