What is a CAR file?
A .CAR file can belong to several different software programs. The most common use is as a Compiled Asset Catalog created by Apple Xcode. Apple developers use these files to store compressed app resources, such as images and icons, for macOS and iOS applications.
However, .CAR files have multiple possible meanings. They can be Carbon Application Archives used by enterprise platforms like WSO2 or 1C:Enterprise. In decentralized web projects, they act as Content Addressable Archives for IPFS. Game engines also use the .CAR extension for vehicle data files in titles like BeamNG.drive and older *NASCAR Racing* games. Additionally, they are used as resource archives for the Solar2D game engine.
How to open CAR files?
Because the .CAR extension is shared by many different programs, the correct software depends on the file's origin. To open an Apple asset catalog, developers use Apple Xcode or the `assetutil` command-line tool on a Mac. If the file is a Carbon Application Archive from WSO2, it is usually a standard ZIP archive. You can open it using extraction tools like 7-Zip or WinRAR. For IPFS archives, you must use the IPFS Desktop software or the IPFS command-line interface.
Best practices and troubleshooting
Guessing the correct software for an unknown .CAR file can be frustrating. Do not change the file extension to force it to open in a specific program, as this will not change the file format and may corrupt the data. Since a .CAR file can be a compiled binary, a ZIP archive, or a game save, you should identify the file structure before attempting to open it.
To remove the guesswork, viewer.online/car can analyze .CAR files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
