What is MIME type "application/vnd.denovo.fcselayout-link"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
application/vnd.denovo.fcselayout-link is a vendor-specific MIME type. It tells software that the file holds a link to a pre-set layout configuration. Files with this MIME type (for example, fe_launch) serve as pointers rather than as data to be read directly.
- Launch Shortcut: It directs the software to load and display a specific interface layout.
- Configuration Link: It contains stored settings or arrangements that the program uses to set up its view.
- Workflow Integration: It helps tie together various parts of an application by triggering a specific visual setup.
This type falls under the application class. It is not meant for regular text editing or media viewing. Instead, it works with proprietary software from Denovo to ensure the layout is launched correctly.
For technical details and standardized information, see the IANA media types registry.

res.end('Content here');
}).listen(3000);

FAQs
What program opens an fe_launch file?
Files with the .fe_launch extension are proprietary shortcuts designed for specific Denovo software applications. Because the MIME type is application/vnd.denovo.fcselayout-link, you must have the corresponding Denovo client installed to interpret the layout instructions and launch the correct interface.
How do I add this MIME type to an Apache web server?
To ensure your Apache server correctly identifies these files, add the AddType directive to your .htaccess file or main configuration. Use the line: AddType application/vnd.denovo.fcselayout-link .fe_launch.
Can I edit an application/vnd.denovo.fcselayout-link file with a text editor?
While you can technically open these files in editors like Notepad++ to view the raw configuration data, manual editing is not recommended. Modifying the internal structure may break the link to the pre-set layout configuration, causing the Denovo software to fail when loading the view.
How do I configure IIS to serve the .fe_launch extension?
In Internet Information Services (IIS), you can add a wildcard MIME mapping in your web.config file. Insert the following inside the <staticContent> section: <mimeMap fileExtension=".fe_launch" mimeType="application/vnd.denovo.fcselayout-link" />.
Why does my browser download the file instead of opening the application?
Web browsers like Chrome and Firefox do not have built-in support for rendering application/vnd.denovo.fcselayout-link content. Instead, they download the file so the operating system can hand it off to the installed Denovo software associated with the .fe_launch extension.
Is the fe_launch file executable?
No, the file itself is not a binary executable (like an .exe); it acts as a pointer or configuration link. However, because it triggers actions within the Denovo software, you should only open files from trusted sources to prevent unintended layout executions.
How do I configure Nginx for this Denovo file type?
Open your mime.types file (usually located in /etc/nginx/) and add the entry inside the types block. It should look like this: application/vnd.denovo.fcselayout-link fe_launch;. Afterward, reload Nginx to apply the changes.
General 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.
