Opening APP files

Did your computer fail to open an APP file? We explain what APP files are and recommend software that we know can open or convert your APP files.

What is an APP file?

Files that contain the .app file extension are executable application program files that are run on the Mac OS X operating system. The APP file format is similar to the Windows EXE file format, but it is used on Mac computers instead of Windows-run computers.

The .app file extension is also used by the Alphacam CAD/CAM computer aiding drafting software program. This CAD application is used for the Woodworking industry and it is often used in the design and manufacturing of various furniture components. The .app files used by this software store the designs that are created by the software.
