How do I clean up the files on my phone?

Last reviewed: October 8, 2026 · Markdown version

Go folder by folder, in the order the clutter arrives — Downloads, screenshots, chat media — and at each stop decide what stays and where it lives before you delete anything. This page is about the files you can see on an Android phone. App caches and "junk" are a different job with their own page, and if the goal is only to free space, start there instead.

Before you start: know what a delete costs

Files by Google's cleaning cards each end on a Move x file(s) to Trash button, and the app's Trash has a deadline: "Files remain in Trash for 30 days and then are automatically deleted." Its own warning about one card is the important exception — "Files deleted from "Junk files" card will be permanently deleted" (Move files to Trash & restore files from Trash, Files by Google Help, read 8 October 2026). So a clean-up is reversible for a month, and only if you use the right button.

1. Downloads

The fullest folder on most phones, and the one where real documents hide among installers. Files by Google has a Delete downloaded files card on its Clean screen (Delete downloaded files, Files by Google Help, read 8 October 2026); open the files you cannot name before you tick them. What is safe to let go, and how to file what you keep.

2. Screenshots

Google's Old screenshots card has a fixed rule: it covers "screenshots created or received more than 4 weeks ago" (Delete your screenshots, Files by Google Help, read 8 October 2026). A screenshot of a booking reference is still worth keeping after four weeks; a screenshot of a meme rarely is, so scroll the selection rather than accepting it whole. Where they are saved.

3. Chat media

The Delete WhatsApp media card follows the same Select files, then Move to Trash pattern (Delete WhatsApp media files, Files by Google Help, read 8 October 2026). Documents people sent you are the part to rescue first — where WhatsApp keeps them and where Telegram does.

4. Duplicates

Google's duplicate card marks one copy for you: "The original file is marked with an “Original” badge. We recommend that you keep the original file" (Delete duplicate files, Files by Google Help, read 8 October 2026). On a Galaxy, My Files has the same idea under Analyze storage, then Duplicate files (Manage and organize files saved on your Samsung Galaxy device, Samsung Canada, read 8 October 2026). Read Samsung's note on that list before tapping: "A confirmation is required to permanently delete the selected files." How matching works, and why names lie.

5. The few very large files

Usually videos. How to list them — and open each before removing it, because the biggest file is often the one you would most miss.

6. Last: empty the Trash, or let it run out

Nothing above frees space until the Trash is cleared or its 30 days pass. Wait a few days, check nothing you need went in, then empty it. That order — decide, file, delete, then empty — is our recommendation, not a vendor's; it is simply the one that does not lose the only copy of something.

Where Adinand Auto File Sorter helps, and where it does not

It covers the "file" step for the folders it watches — Download by default; WhatsApp Documents, Telegram, Bluetooth and Screenshots can be added on Pro. It moves the files sitting directly in them into Downloads › Sorted Files, split by file extension into Documents, Images, Videos, Audio, Apps, Archives and Others, so the decide-and-delete steps above become a look through one category at a time. Sorting never deletes anything. Its free duplicate finder (Android 11 and up) matches copies by their contents, always keeps one, and puts the ones you remove in a trash you can restore from for 7 days. It doesn't clear junk or app caches, and it doesn't find large files for you.
