What is an APP file?

An APP file is an application bundle that runs under macOS, an operating system (OS) developed by Apple and designed to run on Macintosh computers. It stores multiple directories, such as Contents, Resources, and Frameworks, which contain various files that make up the application. APP files are executable files similar to .EXE files in Windows and run when double-clicked.

More Information

Because APP files are macOS packages, you can right-click (or control-click) an application and select "Show Package Contents" to view the files contained in the package. These include resources used by the application, executables, property list (.PLIST) files, frameworks, plugins, icons, and other files.

In Windows and Linux systems, it may be possible to view the contents of a macOS application as if it were a folder. A decompression program like WinRAR may also be able to extract files from a macOS application on other operating systems.

NOTE: Files within an application package should not be edited or moved, since changes may prevent the program from running correctly.
