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.
file type association define that how should a file open. its read the fileextension which is associate with the file. and try to open that file in a particular application thing is called file type association.
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.
Windows can only open files if you have the program associated with that file type installed.
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.
I would need to know the file type before I could give an answer.
Computers use file extensions to determine a file's type.
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.
File extensions are typically three letter abbreviations that identify the type of a file located at the end of the file name.The data files within Windows, for example, have application associated data (for example Music files should be playable by Media Player)- in other words if you have a music file and simply double clicking the music file doesn't launch the correct application; you would need to reinstall the music player application (say Windows Media player.)
Unsupported file types are file extensions that Windows does not know what to do with. This means that there is no program installed on the computer associated with a particular file type. To open an unsupported file type you must first install the program that the file uses to work with it.
