Open HTA File

The HTA file extension is a program that can be run from an HTML document.

In other words, the HTA is an executable file that contains hypertext code and can also contain VBScript or JScript code.

The HTA can be created simply by changing the extension of an HTM file to an HTA extension.

Because it is executable, the HTA is executed by the Microsoft HTML Application Host.

These types of HTA applications can be run on Windows, just by double-clicking on them.

Once an HTA file is double-clicked, Windows opens the application in Internet Explorer and runs the embedded code.

When accessing an HTA file on the web, a dialog usually appears that says:

"What do you want to do with this file?"

• Run this program from its current location
• Save this program to disk
