Create the copy before you need it
Open Watchlist and choose Create backup. Copy every character from the output box into a note or document you control. The text includes supported saved-title references and episode checkpoints. It does not include video, payment information or credentials for a viewing service. Make a fresh copy after meaningful changes if the list matters to you.
Restore by merging
On the destination browser, open NetFilm's Watchlist page, paste the complete text in Restore backup and choose Merge backup. Recognized titles are added without duplicating an existing saved entry. Existing destination checkpoints stay in place rather than being overwritten by the incoming copy. Read the confirmation for added or skipped entries so you understand what happened.
If the backup is rejected
Check that you copied the complete text, not a screenshot, a shortened preview or only the title names. The tool expects a supported NetFilm backup, not another brand's format. It rejects unreadable data instead of guessing. An unknown title or invalid episode is skipped rather than turned into a broken saved card. Your existing list remains the starting point for a merge.
Use the backup controls before clearing browser storage or changing devices. Recently browsed history and external playback progress are not part of this copy. For the meaning of a series checkpoint, see episode help.
