The dell.sdr file contains system information for Dell technical support. It is located in the C:\ directory of Dell computers. The file should not be manually edited or deleted.

SmartDraw uses the .sdr file extension for its drawings. SmartDraw creates high quality diagrams and charts. The files can be opened with SmartDraw to view and edit. SmartDraw can also export the drawings to Office documents, PDFs, JPEGs and GIFs.
The .sdr file extension has low popularity across devices. The files can be viewed on Windows, Mac and the web. They are supported on both desktops and phones. More detailed information is available if needed to open or learn more about these files.
