A safer method
When storage is full, it is tempting to delete quickly. But a large video can also be an important memory. The better method is to start with occupied space, then review the context.
Tasnif does not replace your decision. It makes large files visible, keeps review on device, then lets Apple Photos ask for confirmation if you delete.
Delete only when it is clear
- Screen recordings already shared or no longer useful.
- Long failed takes, camera tests or temporary videos.
- Old large videos already saved somewhere else.
If there is doubt, keep the video. The goal is to recover storage without regret.
