What is MIME type "application/x-ms-shortcut"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
The MIME type application/x-ms-shortcut is used for Microsoft Windows shortcut files. It marks files that launch programs, folders, or documents quickly.
The file holds the target path, icon info, and run settings within a binary structure.
Shortcuts help streamline navigation in Windows. They power quick access from places like the desktop or start menu.
- Provides fast launching of apps and resources
- Stores metadata like working directory and display icon
- Integrates into system menus and toolbars for efficient workflow
This MIME type is associated with files like LNK. For more on MIME types, see MIME on Wikipedia.

FAQs
What is the primary use of application/x-ms-shortcut?
This MIME type represents Windows Shortcut files, which use the .lnk extension. These are binary files used by the Windows operating system to point to an executable program, document, or folder location.
Why do web browsers often block downloads of .lnk files?
Browsers like Chrome and Edge classify application/x-ms-shortcut as a high-risk file type. Because shortcuts can execute arbitrary commands or scripts automatically when clicked, they are frequently used in malware distribution, leading browsers to block them for security.
How do I configure Apache to serve .lnk files correctly?
To ensure Apache sends the correct headers, add the MIME type mapping to your .htaccess file or main configuration. Use the directive: AddType application/x-ms-shortcut .lnk.
Can application/x-ms-shortcut files be used on macOS or Linux?
Generally, no. The .lnk format is specific to the Microsoft Windows shell. While specific utility software on Linux or macOS might be able to parse the binary data to extract the target path, the operating systems cannot natively "run" the shortcut.
What Nginx setting is required for Windows shortcuts?
You should add the mapping to your mime.types file or specific server block. Add the line application/x-ms-shortcut lnk; to ensure Nginx serves the file with the specific identity rather than a generic application/octet-stream.
Why does a downloaded .lnk file look like random symbols in a text editor?
Files served as application/x-ms-shortcut are binary, not plain text. They contain structured data about target paths, icons, and window states that only the Windows OS or a dedicated hex editor can read properly.
Is application/x-ms-shortcut a standard IANA MIME type?
No, the x- prefix indicates it is a non-standard or experimental type defined by Microsoft. There is no standard application/shortcut registered with IANA, making this the de facto standard for Windows environments.
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.
