Why Use WSF

Scripting languages such as VBScript and JScript suffer from the lack of directives like #include or Use.
As a consequence of this it is not possible to create large projects because it is not possible to split the script code to more logical units, separate files. Also, it is not possible to develop code libraries - reusable parts of the code.

Windows Script File can combine more scripts to one project, WSF file. The WSF file can either reference external script files (such as *.vbs, *.js), or contain the scripts. The first is convenient for code libraries, the latter for the project-specific code.

If the project should contain more tasks it is possible to group the scripts to separate jobs. It is possible to run one job of the project, or more jobs at a time.

WSF file can be directly executed by the Windows Script Host.
