What it is

VIP is an older VSM-era format used by Pfaff and Husqvarna Viking workflows. It still appears in legacy design libraries.

Satin Studio behavior

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

Versions and variants

VIP is not VP3 under another extension. Reported files use compressed stitches with behavior similar to HUS.

File identification notes

Treat VIP as a compressed stitch file until proven otherwise. Signature, palette, section boundaries, and decompression behavior are not yet verified in Satin Studio.

Observed structure notes

VIP is still treated here as a compressed VSM-family lead. No complete public byte structure is established in this documentation.
Expect header metadata, thread/color sections, and compressed stitch payloads rather than a raw expanded stream.

Structure sketch

VIP is reported as compressed VSM-family stitch data. Details must be verified per dialect.

struct VipCandidate<'a> {
    header_or_signature: &'a [u8],
    metadata: Option<&'a [u8]>,
    compressed_stitch_sections: &'a [VipSection<'a>],
}

struct VipSection<'a> {
    color_or_thread_metadata: Option<&'a [u8]>,
    compressed_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.
