# What is "space this Mac has marked as reclaimable but has not released yet"?

Some of your disk is marked by macOS as reclaimable — space it can hand back whenever something needs it (often called *purgeable*). It hasn't actually been released yet, and no app can force it; macOS releases it on its own when space is needed.

That's why the free space shown by different apps can disagree. Storage Studio shows this amount separately so you know it's there.
