Emacs Org Text Document

An ORG file may also be a text document created by GNU Emacs, a cross-platform text editor. It stores plain text in the Org mode syntax , which includes simple marks to organize the hierarchy of the text, such as lists, headings, and font variations. ORG files may also contain metadata , such as the title of the document, the author that created it, and the date on which the document was created.

Emacs is an open-source text editing package. Org mode is a major mode included with Emacs by default. The mode was originally created in 2003 by Carsten Dominik and has been updated by various other users.

Org mode is typically utilized to create documents to store organized information. Examples of documents commonly saved as ORG files include to-do lists, notes, and project plans.

You can open ORG files with Emacs, which fully supports the Org mode markup language . Emacs allows you to edit and save the document, as well as convert it to other formats, such as .HTML and .ODT files. You can also convert ORG files to other types of documents with Pandoc on your computer or online in a web browser.

Since ORG files are saved in plain text, you can also open and edit them with a plain text or source code editor. Microsoft Notepad (Windows) and Apple TextEdit (macOS) are text editors bundled with their respective operating systems that support ORG files.

Organya Music File

An ORG file may also be an audio file used by Cave Story, an action-adventure video game released in 2004. It contains music played within the game. ORG files cannot be played by most popular media players, but can be played in OrgMaker.

Cave Story is a Metroidvania-style adventure game that was initially released for Windows. As the game grew in popularity, it was remastered and released on a number of additional platforms, including Nintendo game systems and Steam.

The game's developer, Daisuke "Pixel" Amaya, created and saved much of the game's music in the ORG file format, using a program called OrgMaker. Cave Story's fan community has also created a number of programs that allow them to play, convert, and create their own ORG music.

You can open ORG files with OrgMaker, which is available for download online. The program is primarily available in Japanese, though English and Chinese translations exist.
