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

The .gan file extension is mostly used by GanttProject. It is used to describe project files that users create and save using the GanttProject software. This software is very important for project creators. It is a program that allows users to easily plan, manage, and complete their projects. It can be such a hassle to think about the projects piled up on one’s desk. And if one wants to make the project a success, he or she must not take it for granted. Instead, the project creator would make it a point to plan the project well, in order for the completed project to be as they intend it to be. This is not easy without the GanttProject software. Many features that a user needs for creating a project and ensuring that the results of these projects are good is incorporated in this software. From task building to implementation, this software makes this easy. When users create a project plan, build charts, tables or any supported element using Ganttproject, these are saved using the .gan extension. The projects created and saved using the software are called .gan files. .gan files can be opened with the GanttProject software.

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

Be careful not to rename the extension on .gan 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, .gan. 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.
