Files by Google has two features on the same Clean tab that look almost identical at a glance and do fundamentally different jobs. Review and clean flags junk files that are still on your phone and offers to delete them. Trash is where files land after you have already deleted them, so you can pull them back within a limited window. Confuse the two and you either lose the photo you meant to keep or leave junk sitting on the phone thinking you cleared it.
This is the disambiguation guide. Every claim below matches Files by Google’s 2026 UI (version 1.113x, June 2026 update). If you are looking for the wider tutorial on the Clean flow, our Files by Google review and clean walkthrough covers what each Clean card does step by step. This article is narrower: just the two buttons people conflate.
The one-sentence answer
Review and clean = files still on your phone that Files by Google thinks you don’t need. Trash = files you have already deleted, held for 30 days before permanent removal. Review and clean is a suggestion queue. Trash is a safety net.
Everything below is context for the corner cases where that one-sentence answer is not quite enough.
What “Review and clean” surfaces
The Review and clean header appears at the top of the Clean tab in Files by Google. Under it, the app lists cards for each category of file it thinks you can safely delete. Each card ends in a Select and free up button. Nothing on this list has been deleted yet — you are looking at candidates.
The categories Files by Google flags for review:
- Junk files. Temporary caches the app has confirmed are safe to drop. This is a conservative list — it does not touch the private caches inside
/data/data/<pkg>that only each app can clear from its Storage settings. - Duplicate files. Files that share the same content hash and size. Two saves of the same PDF, two copies of the same APK. Files by Google shows previews so you can spot-check before confirming.
- Downloaded files. Anything in
/Downloadplus media saved by chat apps that opted into Android’s MediaStore exposure — WhatsApp images, Telegram downloads, Drive offline copies. Grouped by app so you can clear one chat history’s worth of photos without losing another’s. - Large files. Anything over roughly 10 MB sorted by size. Videos and installer APKs dominate this list.
- Old screenshots and memes. Screenshots older than the cutoff — default 30 days — filtered by aspect ratio and metadata.
- Backed-up media. Photos that Google Photos has confirmed are uploaded and are still on the device. Files by Google offers to remove the local copy.
Every card requires an explicit tap to confirm. Nothing under Review and clean auto-deletes. If you close Files by Google without tapping Select and free up, the files stay where they are.
What “Trash” holds
Trash is a separate section, usually reached from the Clean tab’s overflow menu or the app’s side drawer depending on your Files by Google version. Everything in Trash has already been deleted — it is not on your phone in the normal sense. It sits in a hidden holding folder for 30 days, after which Files by Google purges it permanently.
What lands in Trash:
- Files you delete through Files by Google’s own long-press-and-tap-Delete flow.
- Files deleted from Google Photos (photos and videos removed there also show in Files by Google’s Trash if the same account is signed in).
- Files removed via Select and free up under Review and clean, in most 2026 builds — Files by Google introduced Trash-first behaviour for the Clean flow in a mid-2025 update, so recent versions route Review and clean deletions through Trash for the same 30-day recovery window.
What does not land in Trash:
- Files deleted by another app (a chat app clearing its own attachments, a browser flushing its download cache).
- Files deleted using a system file manager that is not Files by Google — Samsung’s My Files, for example, has its own Trash implementation that does not overlap.
- Files removed through the Android system Settings > Storage > Free up space flow, which permanently deletes.
You restore a file from Trash by opening the Trash view, long-pressing it, and tapping Restore. It returns to the folder it came from. You empty Trash manually by tapping the overflow menu inside Trash and choosing Empty Trash — that permanently deletes everything held and reclaims the storage.
The mental model
Think of it as a queue and a bin.
- Review and clean is the “should we delete this?” queue. Files by Google raises its hand and says I think you don’t need these anymore. You look. You confirm. Files move out.
- Trash is the “already deleted, still recoverable” bin. Once files leave Review and clean via Select and free up, they go here. From here they either sit for 30 days and disappear, or you restore them.
If the Clean tab shows Review and clean at the top and Trash further down, the top is proposals and the bottom is history. Reading the tab in that order — top first, bottom second — matches the flow of a file: candidate → deleted → recoverable → gone.
When people lose files by conflating the two
Three common mistakes worth calling out because they cost users photos and documents in the wild.
Emptying Trash after clearing Review and clean. Someone runs through Review and clean, taps Select and free up on the backed-up-media card, then opens Trash and taps Empty Trash thinking they are freeing more space. The result: 30-day recovery window collapses to zero on the same photos they just moved. Any photo where Google Photos’ backup confirmation was wrong is now permanently gone. Fix: never empty Trash unless you are certain everything inside is truly discardable. The storage saved by emptying is the same as letting the 30-day timer run out — there is no urgency.
Assuming Trash is where junk goes. Someone opens the Clean tab, sees the Trash section, taps into it looking for the free up space option, finds an empty Trash, and concludes their phone is already clean. Meanwhile Review and clean at the top has 4 GB of duplicates and cached video queued up. Fix: the queue of things to delete is under Review and clean, not Trash. If Trash is empty, that means nothing has been deleted recently — not that there is nothing to delete.
Restoring the wrong copy of a duplicate. After clearing duplicates via Review and clean, someone realises they wanted the copy that got removed rather than the one they kept. They open Trash to restore, but the file preview in Trash is small and the two copies looked identical anyway. They restore, then have to pick again. Fix: before tapping Select and free up on the duplicates card, tap the card to see which specific copy Files by Google plans to remove, and swap the selection if you prefer the other one. Files by Google’s default is to keep the more recently created copy, which is not always what you want.
Trash on Files by Google vs Google Photos vs Google Drive
The three Google apps each maintain their own Trash view, and they do not fully overlap. Photos deleted from one app usually show in another’s Trash, but the recovery windows and delete-permanently buttons live in different places.
- Files by Google Trash — 30-day hold. Restores to the file’s original folder.
- Google Photos Trash — 60-day hold for Photos-uploaded content, 30 days for device-only. Restores to the Photos library.
- Google Drive Trash — 30-day hold. Restores to the Drive folder it came from.
Deleting a photo from Files by Google can also show it in Google Photos’ Trash if the same account synced it. Emptying one Trash usually cascades to the others for the same underlying file. If a photo really matters, do not rely on any single Trash to recover it — check all three.

FAQ
Do files in Review and clean count as deleted?
No. Review and clean is a queue of suggestions. Files listed there are still on your phone until you tap Select and free up on the specific card. Closing Files by Google leaves them exactly where they were.
How long does Trash keep files before permanent deletion?
30 days for files deleted through Files by Google. Google Photos Trash uses 60 days for uploaded photos, and Google Drive Trash uses 30 days for Drive files. The three Trashes are separate but overlap for the same underlying content.
Can I recover a file after Trash has been emptied?
No. Once Trash is emptied — manually via Empty Trash or automatically after the 30-day window — Files by Google cannot recover the file. Google Photos may still hold it if the photo was backed up before deletion; check the Photos Trash separately. Beyond that, the file is gone.
Where does the space go when files sit in Trash?
Trash still counts against your phone’s storage. A file in Trash takes up the same bytes as before it was deleted. The space is only reclaimed when Trash empties — either manually or after 30 days. This is why Trash is on the Clean tab: it is one of the places where “cleaning” can actually free storage.
Does Files by Google’s Trash sync between devices?
No. Trash is per-device. A file you delete on your phone and hold in Trash there does not appear in Files by Google’s Trash on a second phone signed into the same Google account. The exception is content Google Photos also holds — that appears in Photos Trash across devices, but Files by Google’s local Trash view is device-local.
Is Trash on all versions of Files by Google?
Trash was rolled out gradually across 2023–2024 and is universal on recent versions of Files by Google in 2026. Some devices with older builds or region-restricted versions may not show the Trash view. Update Files by Google from the Play Store to guarantee access.
