This article describes how to create a Windows Scripting Host (WSH) script to list the default Multipurpose Internet Mail Extensions (MIME) Map settings for a server running Microsoft Internet Information Services (IIS).
Multipurpose Internet Mail Extensions (MIME) is a way of configuring browsers or mail clients to view files that are in multiple formats based on a MIME Type. MIME Mapping is a process by which IIS maps files by their extensions to a particular MIME Type. For example, a file with a .htm extension has a MIME Type of "text/html," whereas a file with a .gif extension has a MIME Type of "image/gif."
When a request is made by a client for a particular file, IIS uses the MIME Map to determine the correct MIME Type that the client will be receiving. IIS contains a large list of default MIME Types to use, and returns a MIME type of "application/octet-stream" for any file extension that is not explicitly mapped.
When Web administrators create or store new file formats with extensions that may be undefined, the following WSH code may help determine the contents of the default MIME Types list by displaying a sorted list of all current MIME Type definitions.
Listing the Default MIME MapCopy the following WSH code and save it as Mimemaps.vbs:
Run the WSH script from a command prompt using the following syntax:
CSCRIPT.EXE C:\MIMEMAPS.VBS | MOREThe output should be similar to the following:
