What is MIME type "application/vnd.fsc.weblaunch"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/vnd.fsc.weblaunch is a vendor-specific MIME type. It is used to launch web pages or web apps directly from a file.
Files in this format carry configuration details such as a target URL and custom settings. They let applications open a website without manually typing the address. The file uses the FSC extension.

Main use: Automatically starting a web resource with pre-set parameters.
Practical uses: Enterprise tools and vendor-specific applications making web access easier.
How it works: It bundles instructions that a browser or client app reads to launch a specific web page.
Why it matters: It reduces steps by managing links and settings in one file.

This MIME type helps systems recognize that the file should be treated as a web-launch configuration. For further details on MIME types, please visit the IANA Media Types directory.

FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
