What is an ATI file?
Most commonly, an .ATI file is an Animated Character Model Package. These files are created and used by the Drawing Cartoons 2 mobile app and independent games like Friday Night Funkin'. They store 2D character assets, skeletal structures, and animation data. A much rarer use for the extension is the Office Accounting Updated Company File, created by the discontinued Microsoft Office Accounting software to store backup database information.
How to open ATI files?
In their original context, .ATI files are opened by importing them directly into Drawing Cartoons 2 on Android. Because standard .ATI game assets are structured internally as ZIP archives, you can inspect their contents using general archive software like 7-Zip or WinRAR by simply renaming the file extension to .zip. This technical workaround allows you to easily extract individual PNG images and JSON layout data.
Inspecting files with viewer.online
If .ATI has multiple possible meanings for your specific download, we recommend using viewer.online/ati to identify the actual format of the user's file. The platform analyzes .ATI files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because .ATI files use the known ZIP format, viewer.online/ati can safely open and display them online, eliminating compatibility problems.
