About ACG files

The .acg extension is a "chameleon" format used in three distinct, unconnected environments, causing significant confusion for users.

1. Microsoft Agent Preview File (Legacy):
Historically, this is the most common definition. It is a preview file for Microsoft Agent, the technology behind the animated assistants (like Clippy) in Windows 98/XP. Unlike the main character file (ACS), the .acg file only contains a cached graphical preview (Head/Icon) used by the Microsoft Agent Character Editor to display the character without loading the full animation set.

Friction: This format is obsolete. Modern Windows (10/11) does not support Microsoft Agent natively, meaning you cannot "open" these files to see the animation without third-party patches like Double Agent or MASH.
Conversion: Users typically want to convert these sprites to standard images. You can sometimes rename them to raw bitmap formats or use legacy extraction tools to save the frames as BMP or GIF.

2. Broadcast Graphics Package (Professional):
In professional broadcast workflows (approx. 23% of files), an .acg file is a proprietary asset package used by Chyron (specifically AXIS/PRIME systems) or Avid workflows.

The Secret: These are often just renamed ZIP or RAR archives containing standard media assets (PNGs, XMLs).
Solution: If you are a video editor, try renaming the extension from .acg to zip and opening it with 7-Zip to access the internal source files.

3. Audio Comparer Group:
A data file used by Audio Comparer by Bolide Software. It stores the results of an audio scan (fingerprints of music files) to identify duplicates. These cannot be converted to audio; they are purely database records.

Convert.Guru analyzes your ACG file, detects the exact format, and lets you read the text inside.

Users also converted PNG, A3, IWD and PK4 files.
