Different software products use the same extension for different data structures. For example:
- Cached Image Files: Some CAC files are compressed bitmap images used by Caché systems. They store image data in a format designed for quick retrieval. See details at Caché.
- Database Files: Other CAC files use the JetDB format and come from Microsoft Access environments. They may store settings such as plotter driver configurations. More information is available at Microsoft Access.
- Engineering and CAD Cache Files: In engineering software like Aspen Plus, CAC files hold component data and act as caches to speed up CAD-related operations. Visit Aspen Plus for further details.
- PNG-based Files: Certain CAC files follow the PNG standard structure. They might be used as certificate files (PIV) where the image integrity is essential. The PNG specs can be found at PNG Specification.
- Asset Catalog Files: Some CAC files function as asset catalogs in Clip Studio Paint, organizing brushes, tones, and other digital art resources. For more, see Clip Studio Paint.
Use the proper software to open these files as their internal layouts depend on the originating application.
FilExt.com usage tips: Identify the file’s origin to choose the correct viewer or editor. If a file follows the PNG standard, renaming it to a .png extension might make it viewable with common image programs. For database or settings data, use Microsoft Access or specialized tools provided by the related company.
