What is an ACS file?

An .ACS file is a Microsoft Agent Character file.

These ACS files contain the Microsoft Agents created by Microsoft. Microsoft Agents combine animated characters, text-to-speech engines, and speech recognition to improve the interaction between users over the internet.

A great example of an Agent would be "Clippy the Office Assistant". Microsoft provided four characters that you could use for free, known as Peedy, Merlin, Genie, and Robby. You could even create your very own characters using Microsoft's development tools.
