Scripting Runtime DLL Library Overview

This section describes the Scripting Runtime DLL library, scrrun.dll, which offers Dictionary objects to store pairs of keys and values. scrrun.dll also offers FileSystemObject objects for you to manage local file systems.

Microsoft provides a number of runtime objects through a single DLL library: c:\windows\system32\scrrun.dll:

scrrun.dll is available for client-side scripting with IE, server-side scripting with IIS, and shell scripting with WSH. But using FileSystemObject and related objects on the client side with IE is restricted for security reasons.
