File Extension DS

File type: TWAIN Data Source Files

About the DS file type:

If Windows cannot find the appropriate program associated with .DS files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The .DS extension identifies TWAIN data source files. These files are drivers which allow printers and scanners to communicate with each other, and they should be read automatically by your PC (or other relevant hardware, and so there should be no need to view the files directly.

Additional Information:
The .DS file extension also identifies certain chemistry software and SQL Server data source files.
