A DST file is a type of file used in computerized embroidery design. It contains instructions for embroidery machines, telling them where to stitch, what color thread to use, and other important details. DST stands for "Data Stitch Tajima," and it is one of the most frequently used formats in the machine embroidery industry. DST files are typically created using specialized software, such as Wilcom or Tajima DG/ML, which allows users to create and customize embroidery designs.

DST files can be opened using embroidery software or a machine that is compatible with the file format. Some popular embroidery software programs include Embird, PE-Design, and Hatch. If you dont have access to embroidery software or an embroidery machine, there are online tools available for viewing DST files, such as the DST viewer. It allows you to view, zoom in and out, save, and print DST files in a user-friendly manner.

Its worth noting that a DST file may also refer to a drawing sheet set created by AutoCAD, a CAD design and documentation application. In this case, the file contains information in XML format about an organized collection of drawing sheets. To open a DST file in AutoCAD, you need to open the Sheet Set Manager and select the DST file from the Sheet List.
