To clear the cache on a Chromebook, follow these steps:

1. Open the Chrome browser on your Chromebook.
2. Click the three vertical dots (More) in the top-right corner of the browser window.
3. Select "More tools" from the dropdown menu, then click on "Clear browsing data."
4. In the dialog box that appears, choose a time range for which you want to clear the cache, such as "Last hour," "Last 24 hours," or "All time."
5. Check the box for "Cached images and files." You may also choose to clear cookies and browsing history if desired, but clearing cookies will sign you out of most websites.
6. Click the "Clear data" button to complete the process.

Alternatively, you can quickly open the Clear browsing data window by pressing Ctrl + Shift + Backspace on your keyboard

. Additional note: If you want to clear cache for Android apps installed via Google Play on your Chromebook, right-click the app icon, select "App info," then go to "Storage," where you can clear the cache specifically for that app

. This process helps improve performance by removing temporary files and freeing up storage space on your device.
