Opening an HTT File
The HTT file type is primarily associated with Internet Explorer.
What is an HTT file?
HTT files mostly belong to Internet Explorer. A HTT file can work in two distinct ways depending on its source.
HTML Template File:
This type of HTT file is a web template used by Microsoft Internet Explorer. It contains plain HTML code that defines the structure and layout of a webpage.
The file is similar to other HTML files but uses the HTT extension to indicate a template role.

HPTuners Tuning File:
Some HTT files are used by HP Tuners as tuning files. They store parameters and settings for automotive tuning.
The data inside is text-based and can be read by the tuning software.
Use a web browser or HTML editor to view and edit HTML templates. Open HPTuners files with the appropriate tuning software. FilExt.com note: Always make a backup before modifying these files to avoid data loss.

How can I open an HTT file?
You need a suitable software like Internet Explorer to open an HTT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your HTT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a HTT file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert HTT files:
- Internet Explorer
See the previous paragraphs to learn more about the main application. HTT files are often referred to as Internet Explorer web (source)s because this type of file is primarily created or used by this software.
- Hypertext Template File by Microsoft CorporationA hypertext template file controls the look of Windows Explorer when it is showing folder contents in HTML mode. The file is generally called folder.HTT and it typically resides in a hidden sub-folder called Folder Settings. A desktop.ini file maintains the link to it in the form: PersistMoniker=file://Folder Settings/folder.htt. The HTT can have any content and can exploit any available object model to process its data. Any Dynamic HTML (DHTML) page can be used as a folder template. An HTT may also include some environment variables that you cannot access from a regular HTML file. This file can become infected and the W32/Romario-B Win32 worm creates an HTT file as part of its activation. The Mime types used with this association are: text/webviewhtml. This file format is classified as Text. Related links: MSDN HTT Article, W32/Romario-B Win32 Worm
