T01 / T09

Status

What it is

T01 and T09 are tracked as Wilcom-related stitch-stream leads.

Satin Studio behavior

Satin Studio documents this format for identification and inspection. It does not open or export the file.

Versions and variants

Treat each numbered extension separately. The number may identify the underlying stitch encoding.

File identification notes

Reported details:

• .t01: DST-encoded stitch data without the 512-byte DST header.
• .t09: Pfaff-family data lead.

Observed structure notes

• Observed T01 support treats the body as DST three-byte records without the 512-byte DST header.
• T09 remains a Pfaff-family lead with insufficient structure detail here. Treat each numbered extension as its own dialect.

Structure sketch

Treat numbered T files as different leads. T01 is reported as DST body data without the DST header.

struct T01Candidate<'a> {
    dst_records_without_header: &'a [DstRecord], // no 512-byte DST header
}

struct DstRecord {
    b0: u8,
    b1: u8,
    b2: u8,
}

struct T09Candidate<'a> {
    header_or_metadata: &'a [u8],       // Pfaff-family lead, unverified
    payload: &'a [u8],
}

Compatibility evidence

The notes above help identify and inspect the format; they do not imply import or export support. Keep the original file and record the machine and software that produced it.
