Finding things in Finder · Finding what was moved
Why is a folder's size in Storage Studio different from what Finder shows?
Short answer: Storage Studio measures the room a folder really takes on disk, including hidden files at every depth — what you'd get back by moving it. Finder's Get Info shows both size and on-disk figures, and a ≥ means part couldn't be read.
Storage Studio measures how much room a folder really takes up on disk, including everything inside it at every depth and any hidden files — the same amount you'd get back by moving it. Finder's Get Info shows two figures, the size and the space used on disk, and the two often differ.
Other reasons the numbers can differ:
- A ≥ in front of a size means part of the folder couldn't be read, so it's a minimum.
- A folder still being counted shows a spinner, never zero.
- Moved items count as shortcuts in Finder, so they look tiny there.
