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

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

application/x-paperport is the MIME type for files used by PaperPort. It marks a proprietary format that stores scanned documents, images, and related metadata.

In this format, a document is kept as a single file that bundles multiple pages and the configuration details needed for proper viewing. It ensures that the document’s structure, layout, and annotations remain intact when shared between systems running PaperPort.

The file usually appears with the extension MAX.

It houses multi-page scanned documents in one file.
It embeds metadata to help with indexing and retrieval.
It is tailored for workflows that require organized document management and archival.

This MIME type is specialized. It works best when the dedicated PaperPort software is available to open and process these files. For more details on file types, visit FileXT.

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.
