Have you encountered a problem with a IDML file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a IDML file here. In the further part of this page we have added a list of programs that should open your IDML file. It is enough you choose a proper application for your operating system, download and install it.


With the file extension IDML, documents of the DTP (Desktop Publishing) solution InDesign are marked in the so-called InDesign Markup Language Format. With InDesign, for example, you can create print templates and layouts for print products such as flyers, catalogs or brochures.

Imdl files are documents (extension indd), which were saved via the export function of InDesign via 'File -> Export'. An imdl file is a ZIP-compressed archive containing various XML files. So besides the designmap.Xml, which specifies the global document settings and the document layout, there are also Graphics.Xml, Fonts.Xml and Styles.Xml.

The IMDL format is designed for sharing between different InDesign versions and was introduced with the CS4 version as a replacement for the INX format, but can not be processed by earlier versions.

Programs which can open a IDML file

How to open a IDML file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the IDML file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a IDML file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support IDML files. At this point we are looking for disk space where the application was installed in and we can link it with a IDML file. Since then, our operating system will use the selected program to support all IDML files.

Other issues

Despite the described problem with IDML there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the IDML file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the IDML file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
