Can I password protect uploads?

Yes. Set a password in Box Options before starting the upload.

What happens if one file fails?

The failed row stays red, successful files remain available, and WarpBox marks the failed file in the manifest.

Are all options server-backed?

Expiry, password, ZIP download, and one-time download are sent to the backend. Notes like box name, custom slug, and API key mode are saved locally until backend support exists.
