# The Trash and the space it holds

Files in the Trash still take up space. Storage Studio shows how much your Trash is holding, but leaves emptying it to you, because that can't be undone. The one exception is a default rule that clears items left in the Trash for more than 30 days, which you can switch off.

Files you move to the Trash still take up space until the Trash is emptied. Storage Studio shows you how much your Trash is holding, but emptying it is the one thing in the app that can't be undone. So it's never behind a one-tap button: Storage Studio leaves that decision to you, in Finder, where macOS asks you to confirm.

## Where you'll see the Trash

- **What's Using Space** ([Storage Inspector](https://storagestudio.us/wiki/storage-inspector)) lists the Trash with its size, without a Move button, and says why: *Emptying the Trash is the one thing Storage Studio can't undo, so it isn't offered here. Use Free Up Space when you've decided.*
- **Emergency Space** shows *Your Trash is holding* … in a separate note with an **Open Trash** button. The Trash is never part of the plan it builds for you. See [Emergency Space](https://storagestudio.us/wiki/emergency-space).
- **Where Did My Space Go** lists the Trash as a line of its own when it grew, with **Open Trash** and the hint *Emptying it can't be undone, so it's yours to do.* See [Where did my space go?](https://storagestudio.us/wiki/where-did-my-space-go).
- **Smart Care** lists **Empty old Trash items** in its checklist but never runs that step. See [Smart Care](https://storagestudio.us/wiki/smart-care).

## The one automatic exception: old Trash items

Among the default rules that [Free Up Space](https://storagestudio.us/wiki/free-up-space) runs, one clears items that have been in your Trash for more than 30 days. It runs when Free Up Space runs, including the first step of a Smart Care run and the daily automatic run. Items removed this way are gone for good; they don't go anywhere else first.

- Free Up Space runs your rules
  - leads to Is Never delete personal files on?
- Is Never delete personal files on?
  - Yes: leads to The Trash is left alone
  - No: leads to Has an item been in the Trash more than 30 days?
- Has an item been in the Trash more than 30 days?
  - No: leads to The Trash is left alone
  - Yes: leads to That item is removed for good

To stop this, open **Settings** → **Rules** and turn on **Never delete personal files — only move them**. Every Delete rule is skipped while it's on; app-cache cleaning still runs. When the switch is on, a Smart Care summary may mention how much more you could free by allowing old Trash to be cleared, so you can decide.

## Other things that go to the Trash, and stay recoverable

Several features use the Trash as a safety net rather than deleting outright:

- **Delete rules** (old crash reports, old Mail attachments and similar) move items to the Trash, not straight off the disk.
- **Duplicates**: extras are moved to the Trash, so you can put them back. See [Finding and removing duplicates](https://storagestudio.us/wiki/duplicates).
- **Uninstalling an app** moves it and its files to the Trash. See [Uninstalling an app completely](https://storagestudio.us/wiki/uninstalling-an-app).

Things that are still in the Trash keep using space, so the space comes back only when you empty it.

## The Recycle Vault is different

The [Recycle Vault](https://storagestudio.us/wiki/recycle-vault) is Storage Studio's own safety net. Files that Emergency Space and some other features remove are copied there first, normally on your external drive, and kept for six months so you can put them back. It isn't the macOS Trash, and emptying the Trash doesn't touch it.

- **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… (https://storagestudio.us/faq)
- **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… (https://storagestudio.us/faq)
- **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. (https://storagestudio.us/faq)
- **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. (https://storagestudio.us/faq)
