DST Binary Structure & Header Specifications
The .DST format organizes data into validated sequential or hierarchical byte structures. Inspecting the header offset reveals the magic byte sequence 4C 41 3A.
- File Signature (Magic Bytes): 4C 41 3A
- MIME Content-Type: application/x-tajima
- Payload Structure: Optimized data stream with metadata headers and checksum records.
- Safety Classification: Low Risk – Contains machine movement vector commands for computerized sewing and embroidery machines Files ending in .DST should always be inspected for valid magic bytes to verify they match legitimate CAD & 3D specifications.
