.dst

A file with a .dst file extension is a design file intended for embroidery machines. The common .dst extension is a stitch-based file format popularized by Tajima commercial embroidery sewing machines. To open a .dst file typically requires some type of embroidery digitizing software.

The Tajima/.dst format is a dependable commercial format that has been around since before the era of modern computers. Tajima DST file can not store the color palette. It does not have the ability to save RGB (red, green, blue) color values at the color changes. Therefore, the colors the design appears in on-screen are default shades the computer assigns to a 'color change' to help identify what stitches out in the color change.
