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

Files in the WPW extension are also known as developer files, and these can be created using the WinDev software, an application developer program from PC Soft. This software is particularly an IDE application which can be used for the development of mobile programs and Microsoft Windows-based scripts for desktop and laptop computers. Application windows are stored in WPW files associated to specific WinDev projects. Each of these files with the .wpw extension correspond to particular applications developed using the WinDev program. These application windows serve as preview windows and dialogue boxes for WinDev application development projects. When the WinDev software needs to display these application windows, the program locates the WPW files associated to the WinDev projects and references the data stored in those WPW files, so it can display the data contained in those WPW files, which may include a wide variety of visual elements such as buttons, drop down boxes, check boxes, text fields and text messages among others. The WPW is for applications developed for mobile platforms, while WinDev software development projects for desktops and laptops running on Microsoft Windows systems are stored in files appended with the WDW extension.

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

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