.otln File Extension

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

what is a .otln file?

The .otln file extension is associated with the software known as Opal. This software was developed by A Sharp and it is a program that runs on MAC OS. This program is also known as an outlining program and it allows users to organize whatever information they want to organize. Using the Opal software, users can organize their ideas and record them; they can create reports and organize all data contained in the reports created; as well as they can also organize lists and projects, etc. by making an outline for it. This makes it easier for teachers, students and businessmen to create reports, lessons and projects. The outline of the user’s organized information is now saved using the .otln file extension. This is why these organized files are called .otln files. These .otln files can only be opened with the Opal software but with the use of .otln file editor software and .otln file converters, users can transport these files into a friendlier format so that they can be opened even without the Opal software.

how to open a .otln file?

Launch a .otln 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 .otln 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 .otln files aren't yet associated with it. In this case, when you try to open a .otln file, you can tell Windows which application is the correct one for that file. From then on, opening a  .otln file will open the correct application.

A Sharp Opal is an outliner software similar to the famous Acta outliner but what makes it different is that it is intended for Mac OS X and not Windows. This Mac notes and organizer management is available in English as well as in Japanese. Regardless of the language preferred, this program enables you to organize anything essential for business or personal use, which includes notes, ideas, reports, projects, graphics, lists, etc., all in a listed form. Organizing things is much easier and effortless with the use of this software as its interface assists you on how to list down whatever you like and whenever you need it. Reorganizing is not also an issue as it can sort whatever is listed from the most to the least priority. This digital note and checklist program also allows tracking of projects with the use of check boxes and selecting multiple points which make work efficient and quick.

a word of warning

Be careful not to rename the extension on .otln 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.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .otln. 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.
