Help and limits

Download a ZIP with parts and SHA-256 manifest; reconstruct only after every part and whole-file hash verifies. Splitting is not encryption. Do not share parts as if they were protected secrets.

Input up to 80 MB, ZIP up to 90 MB, 320 parts. One operation at a time. Cancel terminates the worker; originals remain unchanged.

Reports can contain private text or headers. Review before sharing.
