What is an AIR file?

AIR files have multiple uses, and Adobe AIR Application is one of them. Read more about the other uses further down the page.

Adobe AIR Application

Files that contain the .air file extension are most commonly used for Adobe AIR applications. AIR is an acronym for Adobe Integrated Runtime.

These files allow developers to build Internet applications that can be deployed to the user's desktop and can run across multiple operating systems. The AIR files are usually compressed using ZIP technology before they are installed on a user's system.

Before being named Adobe AIR, the technology was called Adobe Apollo Rich Internet Application.

All known file formats using extension .AIR

While Adobe AIR Application is a popular type of AIR-file, we know of 2 different uses of the .AIR file extension. Different software may use files with the same extension for different types of data.

Advanced Input Recording

Advanced Input Recording files store sequences of user input events (such as keystrokes or joystick actions) captured during emulator sessions. Emulators generate them when recording gameplay or controller activity to allow playback later, reproducing exactly what the user did. Because these files do not store video or audio, playback means re-emulating the same inputs in the same game environment so the emulator simulates the session as before.

These recordings are created by emulators that support the format, such as RealSpec. During recording the emulator logs each input event along with timing information. To use a file, the emulator is launched in playback mode, reads in the stored events, and feeds them back to the emulated system so the session unfolds automatically. RealSpec's version of this format preceded more open standards that aim for compatibility across different emulators.

Files created in this format begin with the ASCII signature OpenAir! at the very start of the file (bytes 0x4F-70-65-6E-41-69-72-21) to identify them.

Various apps that use files with this extension
