.aca File Extension

Developer: Microsoft Corporation
File type: Agent Character Animation File
You're here because you have a file that has a file extension ending in .aca. Files with the file extension .aca can only be launched by certain applications. It's possible that .aca files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .aca file?

Files stored in the ACA format are data files created and used by the Microsoft Agent software, and this application is for creating animated characters with interactive functionalities. When a Microsoft Agent output file is accessed by a user, this application locates the associated ACA file and retrieves the data stored in the file to reference those details and provide the user with the functionalities integrated by the author of the output project file. These details are relevant for the application to determine the movement, speech and background audio needed to be displayed. Since these ACA files are Agent Character Animation files, it is created by Microsoft Agent with another file in a different format, and this file is associated to the profile data of the animated character. These ACA files can also be opened and edited using the Microsoft Agent Character Editor software. Users of Microsoft Windows-based systems can install the Microsoft Agent application and the Microsoft Agent Character Editor software to access the functions integrated into these programs and implement support into their systems for these ACA files. However, Microsoft Corporation has as of this writing discontinued support for Microsoft Agent and Microsoft Agent Character Editor in the Microsoft Windows 7 OS.

Microsoft Agent Character Editor

Microsoft Agent Character Editor

Microsoft Agent Character Editor is a tool which was developed by Microsoft with the goal of assisting its users to edit their Microsoft Agent which is a compilation of software that gives its users the capability of incorporating animated characters in an interactive manner which is usually being used in some applications and often times with a web page. The Agent Character Editor gives its users the capability of setting the name for their MS Agent while at the same time giving it a short description. The software also consists of an interface allowing its user to control the MS Agent’s behaviour. It enables its user to assemble different types of character animations to be used for their Agent. The program allows its users to outline the different animations based on their liking which is being done with the importation of Windows images and setting of the duration.

a word of warning

Be careful not to rename the extension on .aca files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .aca. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
