Map file used by iMindMap, an application that helps users organize brainstorming sessions; contains a map of the user's central idea, with optional branches, flowcharts, sketches, and text; includes styles, such as Default, Deep Blue, Inspiration, Creative, and Impact; can be exported as a .PDF file.

To create an IMM file, select File → New, choose the Central Idea theme, and select File → Save or Save As.... After the dialog box opens, name the file, choose the save location, and click Save. NOTE: IMM files, which are used by version 4 of iMindMap and earlier, were replaced with .IMX files in version 5. However, iMindMap 5 and later still supports IMM files.
