The VP3 file format appears to be series of nested tagged sections. The files seen so far, start with a header of signature bytes and "Produced by..." string; followed by a tagged embroidery-summary packet. Like Russian dolls, the embroidery-summary packet contains a tagged hoop-centred packet after some information about stitched area, stitching time, etc. The hoop-centred packet expresses a centred stitch extent and contains several tagged thread packets.

Viking/Husqvarna Pfaff/Singer 3 VP3

The VP3 file format appears to be series of nested tagged sections. The files seen so far, start with a header of signature bytes and "Produced by..." string; followed by a tagged embroidery-summary packet. Like Russian dolls, the embroidery-summary packet contains a tagged hoop-centred packet after some information about stitched area, stitching time, etc. The hoop-centred packet expresses a centred stitch extent and contains several tagged thread packets. Each thread packet has colour and weight information, also containing one stitch-rum packet.

The file format could logically contain several embroideries, and each embroidery contain more then one hoop, but this has not been seen. Perhaps to contain a library of patterns, or to split a large design over several hoops.

The tags seen, so far, are,

  • 0 2 0 - Embroidery-summary packet
  • 0 3 0 - Hoop-centred packet
  • 0 5 0 - Thread packet
  • 0 1 0 - Stitch-run packet


In the style of Backus–Naur Form,

File = File-header Embroidery-summary

Embroidery-summary = Summary-details {Hoop-centred}

Hoop-centred = Hoop-details {Thread}

Thread = Thread-details Stitch-run
