Understand the distinction
A household file is useful when each document is connected with the correct product or assessment. A similar-looking manual can belong to a different model. Mixing revisions without labels can also make later advice hard to trace.
Put it in your home notes
Name files with model, document type and revision date where available. Retain the original supplied copy and add notes separately. Keep private identifiers out of public sharing links. A small index helps a future service conversation start from the right information.
