Storage Studio and emptying the Trash automatically

macOS can remove items that have been in the Trash for 30 days. Storage Studio never empties your Trash as part of Smart Care, and keeps the things it removes in its own Recycle Vault.

macOS and Storage Studio look after two different bins. macOS's setting empties your Trash over time. Storage Studio's Recycle Vault holds what Storage Studio removes, so you can bring it back.

What macOS does

In Finder's settings, under Advanced, Remove items from the Trash after 30 days makes macOS delete anything that has sat in the Trash that long. The same switch is offered as Empty Trash Automatically in the Storage section of System Settings. Once an item is removed this way, it's gone for good.

What Storage Studio does

Smart Care never empties your Trash. Emptying the Trash can't be undone, so it's left out of the one-tap routine on purpose.
Storage Inspector shows the Trash but doesn't offer to empty it, for the same reason.
Free Up Space — its default rules include one that permanently clears old items from your Trash. Turn on Never delete personal files — only move them in Settings → Free Up Space and every delete rule is skipped; app caches are still cleared, because apps rebuild them.
Things Storage Studio removes for you go to the Recycle Vault — for example duplicates you clear and apps you uninstall. (Things that rebuild themselves, such as app caches, are simply cleared.) Each item is kept for about six months, with up to a set number of versions of the same file, and can be restored to where it was or somewhere new. It lives on your external drive and never uses more than the share of the drive you allow.

Where removed things go

Using both

They don't overlap. Keep macOS's setting if you like your Trash emptied for you; the Recycle Vault looks after Storage Studio's own removals either way.

Common questions

What's the best app to free up space on a Mac?: If you want space back without losing files, the best approach is "move, don't delete." Storage Studio relocates big apps and folders to an external drive (with a shortcut left in place so they still open), reclaims space macOS is holding in old snapshots, and keeps cloud files online-only — all…
How do I free up space on my Mac?: Empty the Trash, clear app caches, remove old downloads, and move large apps and folders you rarely use to an external drive. Storage Studio does all of this in one tap with Tuhi — it clears caches and rarely-used files, reclaims old local backups, and keeps cloud files online-only, previewed…
How do I get more storage on my Mac without deleting my files?: Pair your Mac with an external SSD and offload what you don't need on the startup disk. Storage Studio moves large apps, folders, and media to the external drive and leaves a shortcut in the original spot, so you reclaim space while keeping every file — nothing is deleted.
Is it safe to clear the cache on a Mac?: Yes — app caches rebuild automatically, so clearing them safely reclaims space; the only risk is deleting the wrong thing by hand. Storage Studio clears only known-safe caches and rarely-used files, shows a preview first, and never touches your personal files without asking.
