APP file extension - Cybiko computer application file

What is app file? How to open app files?

File type specification:

Program executable file type icon Program executable file type

The APP file extension was also used in Cybiko devices.

The Cybiko is a hand held computer introduced in May 2000 designed for teenagers, featuring its own two-way radio text messaging system. It has over 430 "official" freeware games and applications. Because of the text messaging system, it features a QWERTY Keyboard that was used with a stylus.

An MP3 player add-on was made for the unit as well as a SmartMedia card reader. The company stopped manufacturing the units after two product versions and only a few years on the market. However, because of the unique radio messaging hardware there is still a hobbyist community using Cybiko.

Help how to open APP files:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert file with extension APP:

As far as we know, this .app file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
