What is an SDI file?
An .SDI file is most commonly a Windows System Deployment Image created by Microsoft. These files store a bootable disk image. System administrators use them to load and deploy Windows to multiple computers. However, .SDI files have multiple possible meanings. They can also be serialized Dictionary Information files used by the MySQL database server to store table metadata in .JSON format. Finally, some .SDI files are structural analysis projects created by the Soldis PROJEKTANT software.
How to open SDI files?
Because .SDI files can be disk images, database files, or structural projects, you must first know the exact format. You can mount a Windows System Deployment Image using Windows command-line tools or manage them with backup software like AOMEI Backupper. For MySQL files, you can open them with a text editor or database management tools since they contain standard JSON text.
Best practices and troubleshooting
If you do not know the source of your .SDI file, do not modify it. Changing a system image or database metadata file can cause data loss. Because the .SDI extension is shared by completely different software, viewer.online/sdi can analyze .SDI files to identify the exact format and creator software. It can inspect the file structure, extract readable text, and check whether an online preview is available.
Conversion and tools
Once you know what your file is, you might want to convert it. We recommend using convert.guru to change your files into sensible target formats. For example, MySQL .SDI files can often be converted to .JSON or .TXT. Disk images might be converted to .ISO or .VHD.
Summary
viewer.online/sdi is useful for identifying, inspecting, and understanding .SDI files without installing software or dealing with compatibility problems. It helps you safely explore unknown files directly in your web browser.
