What is an IMFX file?

IMFX files mostly belong to Invoicing software. IMFX files are invoice message format containers that package invoice data in a ZIP archive structure.
They follow the Factur-X standard, meaning the file holds both machine-readable XML and sometimes human-readable data for invoices.
Key details compiled by FilExt.com include:

ZIP Archive: The internal format is compressed using ZIP.

Invoice Message: The file carries detailed invoice data for automated processing.

Factur-X Standard: They are used as a container for electronic invoice messages.

Extraction: You can open these files with common ZIP extraction tools to view the enclosed XML or PDF files.

FilExt.com tip: For viewing, use a ZIP file extractor (like 7-Zip or WinZip) and then load the XML with an invoicing or text editor tool designed for such data.

An IMFX file is a Factur-X invoice container, primarily using the ZIP internal file format. Factur-X is a standard for electronic invoicing based on a hybrid approach that combines XML and PDF/A-3, ensuring both human readability and automated processing. The XML portion contains structured invoice data according to the UN/CEFACT Cross Industry Invoice XML standard, while the PDF/A-3 part provides a visually presentable version of the invoice, often including attachments like delivery notes or order confirmations. This combination makes Factur-X invoices suitable for various accounting systems and archiving purposes, promoting interoperability and compliance with legal requirements. This file format is classified as Invoice.

IMFX file format:

The file format determines how the data is stored in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the IMFX files is as follows:

IMFX is a very widely used file extension. The file type predominantly uses a uniform format.

100% of all IMFX files are based on the zip format, so several files are compressed and saved in one IMFX file. An IMFX file can contain up to 8 files (mostly 5 - 8). Customary file names are doc1.pdf, doc1.pdf.p7s, doc1.xml, doc1.xml.p7s, doclist.xml, doclist.xml.p7s and envelope.xml. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. The file size is in the range of 300 KB to 310 KB. The keywords doc1.xmlM are typical for these files. The file name 20180601.imfx is characteristic of these files. These files can be linked to mdeur.
