The File extension APK is an application package used in Android Operating systems. It is actually an acronym standing for "Android Application Package File". What is APK? It is actually the designated file format that is used to install any application software onto devices that are using Android Operating System. Android, which is Linux based platform for mobile phones, was developed by Google in conjunction with Open Handset Alliance. Thus Android applications and games are usually packaged using the file extension APK. Any application installers sourced from elsewhere apart from Google Play Store are usually saved as .APK file. They have to be installed manually and accurately.

You can be able to install APK to your Android device easily. It can be downloaded from the defined sources like Google play store and also from unknown sources. The downloaded file is usually saved in as a compressed or zipped file using the .ZIP extension. To open it you will require a decompression program. Downloading the file from Google Play Store is much safer because it will be free of any malware. This is as opposed to getting it from any other sources that might be infected with malwares that can destroy your Android device.

The file extension is usually indicated as a suffix after the file name. it is separated from the name of the file by a dot. The extension is used to indicate the type of program that should be used to open that specific file.
