Freeing up space · Local snapshots and held space
Do I need the Local Snapshots window after every move?
Short answer: Usually not. After each successful move Storage Studio clears just enough snapshots for the freed space to appear. The window is for older held space and one-off reclaims.
Usually not. After every successful move to your fast drive, Storage Studio clears just enough snapshots for the freed space to show up straight away. If that ever doesn't work, it's noted quietly and never affects the move.
The window remains the right tool for older moves whose space is still held, and for one-off needs such as freeing a set amount before a macOS update. See Custom reclaim.
