Check the Header: Inspect the first bytes in a text editor or hex viewer:
- Readable ASCII text indicates a standard CAD configuration.
- "PK" means it is a compressed archive.
- Unreadable binary suggests a proprietary format.
Use the Original Software: The original program is usually required; common tools include Mentor Graphics PADS and CAM350. If unsure, ask the sender.
