What is IDML file?

Files with the IDML extension are created with Adobe InDesign, and the full name of the format is the InDesign Markup Language. This program is designed for purpose of creating complex graphic layouts of pages, which are later used in magazines, newspapers, brochures, leaflets, books or eBooks. Content of IDML files contains properties of arrangement, metadata, multimedia elements, formatting, and other specific information.

Additional information about IDML files

IDML format is the successor of the INX format, which was much harder to edit using software of other companies – it was less available for software from other companies. Therefore, a new format was created, so that modifying and creating page layouts could be more user friendly also using other applications, not only via Adobe InDesign.

IMDL is a format based on the XML structure, where all of its components are stored within a compressed ZIP package. A single IDML file comprises of files and folders containing elements of a project, arranged according to adequate hierarchy.

Structure of IDML files

Structure of IDML files comprises of the following folders containing project’s elements, and documents and files defining settings and styles of those components:

  • XML
  • Resources
  • Stories
  • Spreads
  • MasterSpreads
  • META-INF

After this operation, the problems with opening the IDML file should be solved.
