DOCM, Word Open XML Macro-Enabled Document (.docm)

The DOCM Document file format

DOCM refers to a Microsoft Word XML format used for text documents in Microsoft Office 2007. It uses ZIP compression to reduce file size. DOCM files are capable of cross-version use between previous versions of Microsoft Word (predating the 2007 version) using the Open XML component support. Windows, Mac, Linux, iOs, and Android devices and programs can open DOCM files, which makes this file format very versatile. Saving files in the DOCM format from Word may ensure most people can open it regardless of their version of Word or OpenOffice.

Technical details of DOCM files

The main difference between DOCM and DOCX files is DOCM’s capabilities to contain macros and VBA scripts within the document. Ease of sending, receiving, downloading, and storing of these files is made possible by the ZIP file compression methods DOCM files utilize. Word documents are capable of large amounts of formatting including images, tables, margins, colors, fonts, WordArt, text alignment, and more. Most features available in other version of Microsoft Word are usable in DOCM compatible files, but converting between DOCM and other files may lead to formatting issues.
