Pfaff Home Embroidery (PCS) is a proprietary stitch data format developed by Pfaff for use with their line of computer-controlled sewing machines. This legacy format stores digitized embroidery designs, including specific coordinates and instructions that translate digital patterns into physical needle movements on fabric. As a specialized vector-like instruction set, PCS files are generally considered safe, though modern embroidery software typically converts them into newer formats like VIP or VP3 for use on contemporary hardware.
