What is an ACD file?

An ACD file is a character definition file created by Microsoft Agent Character Editor. It contains metadata about a Microsoft Agent character, including a list of the frames, animations, audio, and other data that comprise the character. ACD files are used to create corresponding Microsoft Agent characters (typically saved as .ACS files).

More Information

Microsoft Agent is a discontinued program that allowed users to, among other things, create interactive animated characters that could be embedded in software and webpages. Users created these characters using the Microsoft Agent Character Editor.

In the Character Editor, users added and linked together frames that comprised their character's animation(s). They could also add audio the character would speak during its animation's final frame. If the user wanted to save a record of their character's composition, including its image, frames, animations, and other data, they could do so by selecting Save Character Definition. This saved the character's definition as a plain text ACD file.

Notably, ACD files do not themselves contain a character's image, animations, or audio. They contain only metadata used to load the character's image, animations, and audio in Microsoft Agent Character Editor. Therefore, you cannot extract a character's image, animations, or audio from an ACD file.

How do I use an ACD file to build a Microsoft Agent character?

In Microsoft Agent Character Editor, users can use an ACD file to build a character by selecting Build Character from the program's toolbar. This will create either an ACS or .ACF and .ACA file, depending on how you choose to build your character.

How to open an ACD file

You can open and edit an ACD file in Microsoft Agent Character Editor (Windows). If you do not have access to Microsoft Agent Character Editor, you can instead open an ACD file in Microsoft Notepad (Windows), Apple TextEdit (Mac), or any other text editor, to view the plain text data it contains.
