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

In the year 1988, with the release of Windows 2.0, WMF files initially appeared. Later on, Microsoft published the WMF file format specification with the Windows 3.1 release in 1992, and then published a subsequent specification in 2006. WMF files have mainly been replaced by more standard formats, such as .JPG and .GIF images. The WMF format is still supported by different programs, including Microsoft's Windows Photo Viewer, which is included in Windows 7. A file with the .wmf file extension keeps a list of function calls issued to the Windows Graphics Device Interface (GDI) layer, to restore the image. This includes executable code, which can be utilized by some GDI functions that accept pointers to callback functions for error handling. It has point that can store pictures in with smaller file size, in portable form, which can be delivered by processing and parsing the file with the .wmf file extension. Files with the .wmf extension contain a sequence of variable length records having graphics drawing commands, properties and object definitions. The WMF file extension denotes structures for defining a graphical image; because it has commands, property definitions and graphics objects that digitally records an image and can be played back to reproduce that image. This also can be shared among applications and can be used for storing images.

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

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