How to set up Files by Google (Android)
Setup is fast, but it’s worth doing carefully—permissions drive how accurately the app can recommend what to delete.
- Install or update Files by Google from the Google Play Store.
- Open the app. Review the welcome screens and tap to continue.
- When prompted, allow File access / Allow access to media and files. If you see “Allow all the time” options, choose the strongest option the app offers.
- Grant any additional prompts for notifications or Nearby/offline sharing if shown.
- Go to the Clean tab and wait for the first scan to finish. Scans can take a few minutes on slower devices.
If you skip permissions, you may still see some UI, but cleanup recommendations can be incomplete or incorrect.

Core features and how to use them
Files by Google is best treated like a “triage tool.” You review suggestions, decide what’s safe, and only delete what you can live without.
Storage cleanup
The Clean area is where Files by Google highlights items that may be safe to remove, like cached data or downloaded junk. It’s designed to reduce storage pressure without guesswork.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Open Files by Google.
- Tap Clean.
- Review categories such as junk files, screenshots, or cached items (labels vary by version).
- Tap Review if available, then delete items in small batches.
Delete in batches so you can confirm nothing important was removed.
Transfer files offline (device-to-device sharing)
Files by Google supports offline sharing, letting you move photos, videos, and documents without using mobile data. This is especially useful in low-connectivity situations.
- Open Files by Google and go to Send (or Transfer).
- Select the files you want to send.
- On the receiving phone, open the same screen and tap Receive.
- Follow the on-screen prompt to connect using the same device pairing method.
- Confirm the transfer and wait for completion before closing the app.
Share apps and APKs responsibly
Some Android setups can involve APK sharing for sideloading. Files by Google can help locate downloaded installer files, but you should only install APKs from trusted sources.

Find large files and duplicates
Large files—especially high-resolution videos and repeated media—are common storage hogs. Files by Google can surface these so you can delete or move them.
- Open Files by Google and go to Browse.
- Check categories like Large files or Downloads.
- Sort by size if sorting controls are shown on your device.
- Review duplicates and delete only after confirming you don’t need the originals.
Offline backups and media organization (where available)
Depending on your Android version and app build, Files by Google may recommend organizing or managing certain media sets. Treat these suggestions as guidance, not a mandate.
- In Browse, look for media categories like photos and videos.
- Use built-in cleanup suggestions to tidy temporary clutter.
- If the app offers backup-style features, verify where data is stored before enabling them.
Privacy and data handling: what to watch for
Storage and file manager apps sit close to sensitive personal content. Before granting broad access, confirm what permissions you’re giving and whether your setup matches your comfort level.
- Grant only what you need: If a permission screen offers narrower options, pick the least permissive choice that still lets you use cleanup and sharing.
- Review notifications: If you see repeated prompts or unusual activity indicators, check your Android app permissions.
- Be careful with cloud sync: If you delete items locally, ensure they’re also backed up where you expect.
If you manage multiple user profiles on the same device, verify you’re cleaning the correct profile content.

Troubleshooting: when Files by Google fails or underperforms
Most problems are permission or background-process related. The fix usually involves updating the app, granting access again, or adjusting system settings.
The app can’t find files or shows 0 items
If the scan returns nothing, it’s often missing permissions or restricted storage access.
- Open Android Settings → Apps → Files by Google.
- Tap Permissions and ensure storage/media access is enabled.
- Check Battery → Battery usage and disable aggressive restrictions for the app.
- Force stop and reopen: Force stop → open the app again.
- Run a new scan in Clean.
Storage cleanup suggestions look wrong
If the app suggests deleting something you recognize as important, pause and verify before acting.
- Tap Review (or the item list) to inspect exact filenames and categories.
- Delete smaller groups rather than everything at once.
- Confirm the item isn’t tied to a specific app (for example, an offline map cache).
- After cleanup, reboot once if the phone was under heavy storage pressure.
Offline transfer won’t connect
Offline sharing is sensitive to Wi‑Fi/Bluetooth permissions and device compatibility.
Free tools Windows power users keep installed
One-click scans. No signup required.
- Make sure both phones have Wi‑Fi and Bluetooth enabled (or the specific toggles required by your build).
- Disable airplane mode on both devices.
- Keep both phones close (within a few meters) and avoid background app switching.
- On the receiver, open Receive and keep that screen active.
- Restart both phones if the connection fails repeatedly.
Permissions prompts loop or get rejected
If you repeatedly see prompts, it may be because you dismissed the permission or your system policy blocks it.
