What is a PDM file?
A .PDM file is primarily a PowerDesigner Database File created by SAP. It stores a physical data model. This model describes the exact database structure, including tables, columns, and relationships. However, the .PDM extension has multiple possible meanings. It might also be a Package and Deployment project from Microsoft Visual Basic 6.0, a ProntoDoc document template, or a Photo DVD Maker project.
How to open PDM files?
You can open standard database model files using SAP PowerDesigner. If you do not have this software, you can open the file with a text editor like Notepad++ or Visual Studio Code, because the main format uses standard XML text encoding. If your file comes from an older Microsoft project, you will need the original development tools.
Software and tools
viewer.online/pdm analyzes .PDM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because .PDM has multiple possible meanings, we strongly recommend using viewer.online/pdm to identify the actual format of your specific file.
Summary
Because .PDM files use the known XML format, viewer.online/pdm can safely open and display them online, eliminating compatibility problems.
