How to use Google Files to free up space on Android
Running out of Android storage can cause slower performance, failed updates and missing room for photos or new apps. Google Files, the free storage manager from Google, helps you see what is using space and remove it safely. Samsung Galaxy devices and Google Pixels are common in Australia, although the exact menu names may vary slightly between Android versions and manufacturers.
Work through the process in stages rather than deleting files randomly. Start with Google’s automatic suggestions, inspect large downloads and duplicates, then move suitable media to an SD card or cloud storage. Check backups before removing anything, especially when using a capped mobile plan from Telstra or Optus.
Check where your storage is going
Open Google Files and select Internal storage from the main screen. You should see storage used by images, videos, documents, audio, downloads, applications and other files. Android may also show a large System or Other category, which should not be edited manually.
Tap the three-dot menu in the upper corner and choose Analyse storage or Storage analyser. Google will display a breakdown of the largest categories and offer suggestions such as removing large files, unused applications, duplicate images and old downloads. The labels differ between phone brands, so look for an equivalent option if you cannot see that wording immediately.
Let Google Files find easy clean-ups
Choose Clean up or Free up space within the storage analysis screen. Google Files can identify downloads you have not opened for months, duplicate photos, unused apps and large video files. Review each suggestion before confirming, because some cached images may belong to an app you still use.
Automatic clean-up works best for obvious clutter rather than personal data. It normally leaves system files, active application data and recent media alone. Avoid installing another cleaner, as extra apps can consume storage and make the problem harder to manage.
Use a quick cleanup checklist
Start with the lowest-risk items in Google Files:
- Open Downloads and remove old APK installers.
- Check Videos for recordings you have already backed up.
- Delete large ZIP files and duplicate documents.
- Remove unused applications from Apps.
Before deleting anything else, check these important points:
- Confirm that important photos are backed up in Google Photos.
- Keep files needed by offline maps or banking apps.
- Check whether an APK is still awaiting an installation.
- Avoid deleting system folders or unfamiliar database files.
This small pass can often recover several gigabytes without affecting your phone. After completing it, return to Analyse storage to confirm how much space has changed.
Sort through downloads and duplicate media
Downloads are one of the easiest places to find unnecessary weight. Sort the folder by size or date, then look for APK files, screen recordings, podcasts and archives. Browser downloads can also contain installation packages that are no longer needed. Developers should avoid deleting build folders without understanding them; advice about your first programming project can help new learners recognise which generated files matter.
Google Files may group duplicate images and videos under a dedicated suggestion. Open each group, keep the clearest or most recent copy, and remove the rest. If the files are already synchronised with Google Photos, deleting a device duplicate will not remove the cloud copy.
Messaging apps can also accumulate substantial media. Review old photographs, voice notes and documents in the WhatsApp or Telegram folder, keeping anything connected to bookings, receipts or work records. Emptying a conversation’s media does not always remove every cached preview, so check the relevant app’s storage settings as well.
Move files without losing access
If your phone has a microSD card, Google Files can move suitable photographs and videos from internal storage to it. Open the file, choose Move, select the SD card and confirm. Moving large camera files is usually more practical than moving application data, which must remain on internal storage for reliable access.
Google Drive, OneDrive and other cloud services provide another option. Save documents to the cloud or mark them as available offline. Run large transfers over home Wi-Fi rather than mobile data, particularly if your Telstra or Optus plan has a limited allowance. For commuters in Sydney and Melbourne, checking oversized downloads before leaving home can prevent unnecessary data usage.
Keep a backup of anything moved to removable storage. SD cards can fail or be lost, and some applications work better when their data stays on the phone. Eject the card through Android’s notification shade before removing it, and do not disconnect it while files are still transferring.
Reclaim space from apps and games
The Apps section of Google Files shows which applications occupy the most room. Uninstall games, old shopping apps and services you no longer use. For an app you want to keep, open Android’s Settings > Apps, select it and clear its cache where that option is available.
Clearing the cache can reset an app’s performance, while clearing its data may remove preferences, offline content or account information. Avoid clearing data for banking, navigation and authentication apps unless you know how to sign in again. The required clearance steps can also differ between stock Android and Samsung’s One UI.
Games often need special care. A title like State of Survival may contain downloaded assets and cached updates that can be restored, but clearing its data could also remove local settings. Clear the cache first, then reinstall the game through Google Play if necessary. Check paid subscriptions separately after uninstalling, since Google Play bills Australian accounts in AUD and removing an app does not automatically cancel a recurring purchase.
Keep storage under control
Make storage maintenance part of your monthly routine. Open Google Files, run Analyse storage, review your Downloads folder and remove any new recordings or installation files. Aim to keep at least 10 to 15 per cent of internal storage free so Android can install updates and maintain temporary files without becoming sluggish.
Open Google Files now and complete one cleanup pass: review the suggested items, delete a handful of unnecessary downloads and move one large media folder to safe storage. Your phone will have more breathing room, and the next storage warning will be easier to handle.
