What is MIME type "application/x-lrzip"?

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-lrzip identifies files compressed with the LRZIP algorithm. It is optimized for large files that contain long sequences of redundant data.
The emphasis is on achieving high compression ratios and faster decompression compared to older methods.

Efficient compression for extensive backups and archives
Ideal for log files and large datasets with repetitive content
Popular on Unix-like systems with tools available for other platforms

Files in this format typically use the extension LRZ.
The approach is suitable for scenarios where saving disk space and managing large file sizes is essential.

Usage Examples

HTTP Header

When serving content with this MIME type, set the Content-Type header:


    Content-Type: application/x-lrzip

HTML

In HTML, you can specify the MIME type in various elements:


    <a href="file.dat" type="application/x-lrzip">Download file</a>

Server-side (Node.js)

Setting the Content-Type header in Node.js:


    const http = require('http');
    
    http.createServer((req, res) => {
      res.setHeader('Content-Type', 'application/x-lrzip');
      res.end('Content here');
    }).listen(3000);

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.
