You're here because you have a file that has a file extension ending in .org. Files with the file extension .org can only be launched by certain applications. It's possible that .org files are data files rather than documents or media, which means they're not meant to be viewed at all.

The .org file extension is mainly associated with Lotus Organizer; software that allows the creation and storage of personal information as well as other information such as tasks and to-do lists, contacts and a lot more. This software is popularly known as an electronic day planner and the files that are created using this software, the files containing the user’s personal information are called .org files. But aside from Lotus Organizer, there are also other applications associated with the .org file extension. The extension is also used by Microcal Origin; software mostly used by scientists as well as engineers for their data analysis. The data created using this software and the data being analyzed to help them with their experiments are called .org files which can be opened using the Microcal Origin Pro  software. Another application associated with the .org file extension is the Odds Ratio Generator. Files created using this software are also called .org files. The software is used to compute data such as Odds ratios, events rate, etc. and all these data are saved into the .org format. The .org files are also called organ or sound files used by the Yamaha organ software and these files contain information about flute files that contribute to its simulation. There are also other applications using the .org file extension such as Hollywood FX, Netmino File as well as Pinnacle applications.

Launch a .org file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .org file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .org files aren't yet associated with it. In this case, when you try to open a .org file, you can tell Windows which application is the correct one for that file. From then on, opening a  .org file will open the correct application.

Be careful not to rename the extension on .org files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .org. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
