WSF files are Windows Script files that are executed by an interpreter. In essence, they are text files that contain code in Extensible Markup Language (XML). Windows Scripting is quite flexible and language-independent by the support of different scripting languages. Windows Script acts as a kind of container and can include Visual Basic Script, JScript, or Perl and Python.
To view or edit WSF files, a simple text editor is sufficient. Also Visual Studio can deal with WSF files and debug them.
To run WSF files you need the Windows Script Host. This has been part of the standard installation since Windows 98 SE, in which only Visual Basic Script and JScript are supported. Other scripting languages must be installed by script module. If the Windows Script Host is installed, you can simply start WSF files by double-clicking like an exe file.
Caution is recommended for unknown WSF files as they may contain viruses.
Most often resolving problems with opening WSF files is very simple. Just install an appropriate program that supports such files. All of the listed programs support WSF files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of WSF files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate WSF files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Microsoft WScript applications is not on the list, select "Browse" option in order to manually locate the directory where Microsoft WScript has been installed.
Sometimes problems with opening WSF files may not lie with the application itself, but can arise due to other causes, such as:
