Quick Answer
Go to Settings > Device > Storage management to see a breakdown of what’s using space. Clear the browser cache, offline files, and Downloads folder first, then check Linux (Crostini) and Android app storage separately, since both sit outside the main file browser. A Powerwash should be the last resort, not the first step.
What’s Actually Using Your Storage
Most Chromebooks ship with 32GB to 128GB of local storage, and it fills up faster than expected from a few specific sources: offline-synced Google Drive files, downloaded videos and PDFs sitting in the Downloads folder, browser cache, installed Android apps and their data, and Linux (Crostini) containers if you’ve set one up. Cloud-stored Drive files themselves don’t count unless you’ve marked them “Available offline.”
Fix Steps
Step 1: Open Storage management
Go to Settings, then Device in the left sidebar, then Storage management. This shows a breakdown by category: My files, Apps, Browsing data, and (if installed) Linux.
Step 2: Clear browsing data
Tap “Browsing data” in Storage management, or go to Settings > Privacy and security > Clear browsing data and check “Cached images and files.” This alone can free several gigabytes if you haven’t cleared it before.
Step 3: Empty the Downloads folder
Open the Files app, select the Downloads folder, and delete or move anything you no longer need to Google Drive, which doesn’t count against local storage. Sort by size to spot the largest offenders quickly.
Step 4: Remove offline Drive files you don’t need
In the Files app, go to your Google Drive folder, right-click any file or folder marked “Available offline,” and toggle it off. The file stays in Drive but stops taking up local space.
Step 5: Check Android app storage
In Storage management, tap “Apps” to see which Android apps are using the most space. Uninstall ones you don’t use, or clear an individual app’s cache from Settings > Apps > [app name] > Storage.
Step 6: Manage Linux storage separately
If you’ve installed Linux, its disk allocation is fixed and doesn’t shrink automatically as you delete files inside it. See our guide on managing Crostini containers and disk space to reclaim space there.
Still Not Fixed?
If storage is still nearly full after clearing cache, downloads, and offline files, run the built-in Diagnostics app to confirm the actual free space matches what Storage management reports. If a large, unexplained gap remains, a Powerwash is the fastest way to reclaim everything at once, though it should be a last resort since it erases local data.
FAQ
Does deleting a file from Google Drive free up local storage?
Only if that file was marked “Available offline.” Files that only exist in the cloud were never using local storage in the first place.
Why does my Chromebook say it’s low on storage right after a Powerwash?
Some space is reserved by ChromeOS itself for system files, updates, and swap space, so the usable total is always a bit less than the advertised capacity, even on a freshly reset device.
Can I add more storage with a USB drive or SD card?
Yes, external storage works for files, but installed apps and the operating system itself must stay on internal storage, so it doesn’t help with app-related space issues.
