What is an .ASEC file?

.ASEC is Android Secure Application File

An ASEC file is a secure application introduced with Froyo, the version 2.2 release of the Android mobile operating system. It stores mobile application data using proprietary encryption and is saved to the .android_secure folder of a device's SD card. ASEC files can be run with the Android SDK emulator.

The secure ASEC format allows applications to exist on mobile devices without being modified or corrupted by other programs.
