You’re here because you have a file with a .gan extension. The .gan file extension is mostly used by GanttProject for project files. Files with this extension are data files, not documents or media. They are not meant to be viewed.
What is a .gan file? GanttProject software uses it to save user-created project files. The software is important for project creators.
Sometimes you just need to see the contents of the .gan file without performing complicated operations. A .gan Viewer allows displaying the file’s contents.
The system may not handle the .gan opening program if under heavy load. In this case, close other applications first. Check for the latest OS and driver updates as well. Regular updates keep your computer secure and may prevent issues with .gan files.
It may be that updated software addresses some .gan file system bugs.
Associating the .gan extension with corresponding software in Windows Registry is difficult.
Many files contain only simple text data. Below are tips on opening .gan files and programs that support them.
You need to update the application you normally use to open .gan files. Only the latest version supports the current .gan format.
You need to check the .gan file for viruses with a popular antivirus (Norton, Nod32, Kaspersky, Dr.Web, etc.).
When you double-click a file to open it, Windows checks the filename extension. If Windows does not recognize the extension, you receive a message to select an app. It means the OS does not have a default .gan file type app.
