What is a .HTT file?

The .HTT file extension stands for Hypertext Template. This type of file is a hypertext document, which means it is a type of file used on the internet or within computer systems to link different pieces of information together using hyperlinks. Specifically, .HTT files are used to set up certain preferences or settings within the Windows operating system. One common example of a .HTT file is "Folder.htt." This file contains HTML code, which is the standard language used to create and design web pages. However, instead of creating a web page, this HTML code is used to customize how the contents of a folder look on your computer. It can change the way files and folders are displayed by adding custom designs, layouts, or even interactive scripts. These scripts can perform tasks like fetching and showing details about the files contained in the folder using a component known as the FileList control.

To open or edit .HTT files, you don't need any special program outside of what Windows provides, since the operating system itself references and uses these files. However, if you want to view or modify the HTML code inside a .HTT file, you can use a simple text editor like Notepad, which comes pre-installed on Windows computers, or more advanced code editors like Notepad++ or Visual Studio Code. These programs allow you to see the code and make changes if you know how to write or edit HTML and scripts. Remember, making changes to .HTT files can affect how folders are displayed on your computer, so it's a good idea to have some understanding of HTML and scripting before attempting to modify these files.
