.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. For that reason, the 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.
Even though the (.dst) data does not contain specific thread color information, the Tajima file type remains the most common format found in the embroidery industry.
.DST file naming convention
The correct naming convention for a Tajima DST file is gXXX.dst where the letter g is lowercase and the 3 X are numerical values from 001 - 099 not to exceed or equal 100. If a user does not abide to these naming conventions it is possible that the embroidery machine will not read, view or recognize the embroidery design.
