About .pie Files

PIE files are XML-based files used by Poste Italiane for their Email Digital Postmark system.
They follow the MIME type text/xml, which means they store data as plain text in XML format.
This file contains digital stamp information that validates email transmission and timing.
It holds metadata such as timestamps, sender details, and verification tokens.

Based on information from FilExt.com, PIE files serve as a trusted digital postmark mechanism for secure email communications.

Relationship between file extension and MIME type

A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.

File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.

File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs

What is a .pie file?

A .pie file is a digital postmark file used by Poste Italiane for their Email Digital Postmark system. It is an XML-based file that contains metadata, timestamps, and digital signatures to validate the authenticity and timing of an email transmission.

How do I open a .pie file?

Since these files are formatted as text/xml, you can view their raw contents using any text editor such as Microsoft Notepad, Apple TextEdit, or Notepad++. However, to verify the digital stamp legally, you typically need specific software provided by Poste Italiane or a compatible PEC (Posta Elettronica Certificata) client.

Why did I receive a .pie file attachment?

Can I convert a .pie file to PDF?

You can print the text content of the XML code to a PDF using a text editor, but this destroys the digital validity of the file. The .pie file must remain in its original digital format to serve as valid legal proof of the digital postmark.

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 can one extension have multiple MIME types?

Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
