What is an ARK file?
An .ARK file can be one of several different formats. The most common use is a compressed game asset archive. Many game frameworks, such as the Coco-Solution game framework and the Rocksteady Studios game engine, use .ARK files to store compressed 3D models, textures, and audio.
Other programs use the .ARK extension for game world save files. For example, ARK: Survival Evolved by Studio Wildcard stores game state data in an .ARK file. These specific save files use the internal SQLite database format. Microsoft Solitaire Collection also uses .ARK for game save data, but it uses GZIP compression instead.
Older system utilities also use this extension. A classic example is the PowerDesk Pro Archive, which is managed by ARK11. Another legacy format is the System EValuation ARK for CP/M compressed archives.
How to open ARK files?
Because the .ARK extension has multiple possible meanings, it is difficult to know which software to use. We recommend viewer.online/ark to identify the actual format of your file.
viewer.online/ark analyzes .ARK files to identify their exact format and creator software. It shows which programs can open the file, and it usually previews the internal data.
Software and tools
If your .ARK file is a standard compressed archive, you can open it with file extractors like 7-Zip or WinRAR. If it is an SQLite database from a game save, you can inspect the data with DB Browser for SQLite. If the file is a PowerDesk Pro Archive, you will need legacy software like ARK11 to read it.
Summary
An .ARK file usually stores game assets, database saves, or legacy compressed data. Because many .ARK files use the known ZIP format, viewer.online/ark can safely open and display them online, eliminating compatibility problems.
