Files by Google (formerly Files Go) is one of the most useful pre-installed tools on Android — and one of the most ignored. It doesn’t just organize files; it actively finds hidden storage wasters and helps you clean them up in a few taps.
Short Answer: Open Files by Google → tap the Clean tab → follow the suggestions. It finds backed-up photos, duplicate files, downloaded APKs, and large unused files, often recovering 3–10GB with minimal effort. It also has the best offline file-sharing feature on Android.
How to Use Files by Google’s Clean Feature
- Open Files by Google (pre-installed on Pixel phones; available free on Play Store for all Android phones)
- Tap the Clean tab at the bottom
- You’ll see categories of space-wasting content it has found:

What It Finds and Cleans
Junk Files (Biggest Win)
Temporary files, app residue, partial downloads, and cache from apps that have been uninstalled. Tap “Clear junk files” and confirm. This is safe — no personal data is deleted.
Backed Up Photos
If you have Google Photos backup enabled, Files by Google identifies all photos on your device that are already safely backed up to the cloud. You can remove the local copies while keeping the originals in Google Photos. Often recovers 5–10GB.
Old Downloads
Shows files in your Downloads folder sorted by size and age. Review and delete PDFs, APKs, and documents you downloaded months ago and no longer need.
Large Files
Lists the biggest files on your phone — videos, large APKs, archives. Gives you a visual hit list of what’s eating your storage so you can make informed decisions about what to keep.
Duplicate Files
Finds identical files stored in multiple locations (common with WhatsApp media, downloaded songs). You keep one copy and delete the rest.
Offline File Sharing (Nearby Share)
Files by Google has a built-in Nearby Share that transfers files between Android phones over Bluetooth/Wi-Fi — no internet required, no QR code scanning, no apps on both phones needed beyond Files by Google.
- Open Files by Google → Browse → select a file
- Tap Share → Send nearby
- The recipient opens Files by Google and taps Receive
Much faster than Bluetooth alone — transfers at Wi-Fi speeds without needing the same Wi-Fi network.
Enable Smart Storage:
In Files by Google settings, turn on Smart Storage. This automatically removes device copies of photos that are already backed up to Google Photos when your phone’s storage drops below a set threshold. Set-it-and-forget-it storage management.
Quick checklist:
- ✅ Clean tab → Clear junk files: always safe, often recovers 1–3GB instantly
- ✅ Backed up photos section: removes local copies already in Google Photos
- ✅ Old downloads: delete forgotten PDFs, APKs, and attachments
- ✅ Enable Smart Storage for automatic cleanup when running low
- ✅ Use Nearby Share for fast offline file transfers between Android phones
