Determining Unknown File Extension

The Windows Registry contains settings that determine the application used to open file extensions. Once set this means that whenever you attempt to open a file of a specific type your Windows operating system will use that same application.

Because of the number of different file types that are used it is fairly commonplace to receive or acquire files with an unknown file type. In most cases users need to find the appropriate application before the file can be opened, but certain precautions should always be taken before attempting to open any unknown file types.

How to Open Unknown File Extension

The first step in opening an unknown file type is to try to determine the software you will need. Later in this guide is a list of common file extensions and the application or applications that can be used to view or edit these files. With literally thousands of different extensions it is not possible to include every single one in this guide, but those that are not included can usually be found by searching online using the extension as the search phrase. Once you have found the application you will need, download and install it to your computer and then open the file.

Depending on the application you may be prompted when installing the program to determine the file types you wish to open with this software. Alternatively, when you attempt to open a relevant file extension and are prompted to decide on the software to use you should tick the box to open all files of this type with that software. In the future when you attempt to open files of this type your Windows operating system will know the application to use in the future.

Every file type is structurally different. Without using the proper application to open a file the architecture of the file can not be read and the file can not be viewed or edited properly. For this reason, the biggest part of the challenge of opening an unknown file type, is finding the proper software that is most closely and regularly associated with that file structure.

A little known method of solving this problem is repairing the registry associations that led to the corrupted file extension in the first place. We suggest trying RegCure to diagnose and repair any potential problems in this area. This is the simplest way of solving the problem for good.

Associating a File Extension With an Application

The Windows registry contains a number of entries that are associated with the opening of each file type present on your computer. Associating a file extension with a specific application means that the Windows Operating System will consult the Registry and determine that the associated program should be used to open that type of file. Windows will then automatically use this application in order to open files of this type in the future.

Associating applications with extensions can save a good deal of time in the long run. Instead of having to manually select the application to use whenever you attempt to open a specific type of file, Windows can automatically use the same application each time.

Third Party File Extension Preview Software

Even genuine file types can cause problems. Namely, if you do not have the appropriate application to open a file then it is highly likely that you will struggle to open the file and view its contents never mind edit it. In some cases, though, it can be possible to use third party applications to view or preview files. This is especially true with media files such as images or movies.

Windows Media Player can normally be used to view images and videos and listen to audio. However, should you wish to change the contents of the files then you will need to have the appropriate application installed. In order to help out we have listed 50 of some of the more popular and common file extensions as well as details regarding the file type and how you can view and edit the files.

Top 50 File Extensions And Their Associated Programs

This is a list of some of the more popular program extensions as well as the applications that are most commonly used to view or edit the files. Notes are also included regarding any other methods that can be used to view or preview the content of the files before fully opening them. While this list is not a complete list of every single extension type available it is an extensive list that includes the vast majority of popular extension types that you are most likely to come across.
