Opening IDF files

Did your computer fail to open an IDF file? We explain what IDF files are and recommend software that we know can open or convert your IDF files.

What is an IDF file?

The .idf file extension is most commonly associated with MIDI instrument definition files. The IDF files define the parameters of a MIDI instrument or controller. These files provide the instrument ID, key map, channel assignments and other necessary MIDI information.

The .idf file extension is also used for identification files, InspireData files, Printed Circuit Board data exchange files and Autodesk intensity duration frequency factors data files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
