About VSDM File Format

Files with VSDM extension are drawing files created with Microsoft Visio application that supports macros. VSDM files are OPC/XML drawings that are similar to VSDX but also provide the capability to run macros when the file is opened. Macros are user-defined actions/steps that are developed in Visual Basic for Applications (VBA) and can be used to perform repetitive tasks.
