You can find out the file type by searching on http://filext.com/ and then you can see what programs you can use to open that file. Hope this helps.
Most of the time if you first open the correct application, you can then use it to open a file that is of the correct format, even if the file type is not correctly associated with the extension. On the other hand if you click directly on the file and the file type is not associated with the correct application, it usually will not open - or at the very least will give you weird results when it opens up with the wrong application.
This is done by the programs that can open the file type in the designated format. for example a .AI file is opened by Adobe Illustrator because the Adobe Illustrator program sets a value in the computer to indicate it can open the .AI file, this is usually done automattically, but can also be done manually. the programs that can open file types have the file type listed as an "associated file type.

In Microsoft Windows, when a file is double-clicked, the operating system attempts to open the file using the default application associated with its file type. For example, double-clicking a .txt file typically opens it in a text editor like Notepad, while a .jpg file might open in an image viewer. If no associated application is found, Windows will prompt the user to select a program to open the file. Additionally, if the file is executable (like a .exe), double-clicking it will run the program directly.
There are many reasons that a file cannot be opened. The most common one is if you are trying to open a file of a certain type with the wrong kind of application. So for example, you cannot open a spreadsheet file with a graphics program. So it is important to open the file with the correct application and the correct version of that application.
The default application that opens a file type can be found and changed for any file. Click the file and press command i. A window will open with information (i) about the file. One of the items is the name of the default application that will open that type of file. Click that and other apps that can open the file will be listed. You can select a new app and have it open that particular file or all the files of that type. You may need an administrator's name and password to do this.
Windows can only open files if you have the program associated with that file type installed.
To open an RCG file, you typically need to use the software that created it, as RCG files are often associated with specific applications like data analysis or configuration tools. If you know the program that generated the file, launch that application and use the "Open" option in the menu to locate and open the RCG file. If you're unsure of the associated software, try searching online for the file type or check for any documentation related to the file. Additionally, some text editors might allow you to view the contents in a raw format if it contains readable text.
Computers use file extensions to determine a file's type.
In Microsoft Windows, when a file is double-clicked, the operating system typically launches the default application associated with that file type.

I would need to know the file type before I could give an answer.
Hold down the shift key and right-click on the file. From the menu select 'Open With...' and Windows will present a list of possible applications it thinks you might want to use. If the application you want is not in the list you can select the 'browse' option and navigate to the application you want. If you want to use the same application for all other files of this type, put a tick in the box labelled 'Always use the selected program to open this kind of file'. This will change Windows association for that kind of file to the application you have chosen. In most cases this action will also change the icon that Windows uses to represent that file type to indicate the application in which it will open.
