Why convert 001 to ZIP?
A multi-part split set requires all numbered files with exact names kept together. A single .zip archive is self-contained and opens on any OS without extra software, making it simpler to share or archive.

copy /b file.001 + file.002 file.zipon Windows without extra software, then verify the result opens correctly.
