What is MIME type "application/x-spss-por"?

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-spss-por identifies a portable file used by SPSS. It stores statistical data in a text-based (ASCII) format. This makes data exchange easier between different operating systems.

Files with this MIME type use the POR extension. The text format allows the file to be read on various platforms without compatibility issues.

Data portability: Enables smooth transfer of statistical data between systems.
Cross-platform support: ASCII encoding ensures the file works on Windows, macOS, and Linux.
Legacy compatibility: Useful for opening data files with older versions of SPSS and other statistical software.

The x- prefix indicates it is a vendor-specific type. For more details on SPSS and its file formats, visit IBM SPSS Statistics.

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.
