Design assets, templates, and course bundles benefit from clear folder structures, changelogs, and readme notes. Offer lightweight previews to reduce refunds. For audio or video, compress wisely to balance quality and size. Communicate updates proactively so customers know when improvements arrive and why downloading again is worthwhile.

Time-box access when relevant, and combine with watermarking. Make renewals clear, fair, and automatic to preserve revenue without creating extra support overhead or confusion.
