File Format Description

Encoded file created by the Flash compiler when compiling ActionScript scripts (.AS files); contains bytecode for the script, which is compiled code that is readable and executable by the ActionScript Virtual Machine (AVM or AVM2); often dynamically generated by the runtime compiler, so the user may not ever see the ABC file.

ABC files are created in a format known as the "abcFile structure." This structure is comprised of primitive data, structured data, and arrays. Primitive data include integers and floating point numbers, while structured data includes an executable code block with its constant data, type descriptors, code, and metadata. Arrays are comprised of both primitive and structured data.

NOTE: The ActionScript Virtual Machine is included with Adobe programs such as Flash and Flash Player. However, ABC files are only meant to be run by the virtual machine, not edited with these programs.

File Format Description

Music file created in the ABC musical notation language, which stores the composition in a plain text ASCII format; can be translated and laid out in an actual score and also played back using an ABC-compatible application.

ABC files can be converted to the MusicXML format using the Web service called Abc2xml. This service is also used by MuseScore for importing ABC files (as a preinstalled plugin). You can import ABC files in MuseScore by selecting Plugins → ABC Import.
