VSDM is a relatively recent extension introduced for Microsoft Visio, launched as part of the Microsoft Office 2013 pack. The format represents an upgrade of Visio's former proprietary extensions: VSD and VDX. VSDM files contain vector drawings that can store and execute macro images when opened. They are only compatible with Visio 2013 and they tend to have a large size, so for easier storing, transferring and accessibility, we recommend converting them to more widely used formats.
