File Type:	Mac OS X Application   (Most common)
Popularity:	5
Category:	executable
File Description:	Application program (or executable file) that runs under Mac OS X; runs when double-clicked; similar to a .EXE file in Windows. Because APP files are Mac OS 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, property list (.PLIST) files, frameworks, plugins, and other files. In Windows and Linux systems, it may be possible to view the contents of a Mac OS X application as if it were a folder; a decompression program like WinRAR may also be able to extract files from a Mac OS X 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.
