Identify the Source: Receiving this from an apparel designer or a textile engineer suggests it may belong to Gerber CAD workflows.
Check the Header: Open the file in a text editor or hex viewer to inspect the first bytes:

- "PK" indicates a standard ZIP archive.
- Unreadable symbols often mean it is a proprietary binary format.
Use the Original Software: The original program is usually required; try Gerber Design Engineered Interface, Gerber AccuMark, or ask the sender if uncertain.
