Why sorting by size changes the review
A library can contain many small images and a few very large media files. Without a size signal, you can delete for a long time without recovering much space.
Tasnif focuses on occupied space. Start with high-impact media, review items calmly, then keep what still matters.
What to check first
- RAW, ProRAW and imported photos.
- Screenshots, bursts and similar batches that pile up.
- Long or old videos that weigh more than photos alone.
Your media stays on device. Tasnif deletes nothing automatically, and Apple Photos asks for confirmation if you choose to make space.
