How to Delete Temporary Files on Chromebook

Remove temp files and system junk left behind by installations and updates.

Last verified: February 21, 2026

Chromebook doesn't accumulate traditional temp files in the way Windows does — Chrome OS stores most application state in the browser's own cache rather than system-level temp folders. The practical equivalent is clearing Chrome's browser cache (Ctrl + Shift + Delete), clearing the Downloads folder of files you no longer need, and periodically removing offline Google Drive content using the Files app. A complete Powerwash returns the OS to its clean factory state if the device has accumulated significant caches from heavy Android app use.

Quick Steps

Follow in order for the fastest result.

  1. 1Open Files app > Clean to remove offline files and junk data accumulated by the OS.
  2. 2Also open Disk Cleanup from the Start menu (Windows) or use Storage Recommendations (macOS) for deeper system temp file removal.
  3. 3Empty the Recycle Bin or Trash after deleting to complete the cleanup.

Frequently Asked Questions

Is it safe to delete temporary files on Chromebook?
Yes. The Files by Google or built-in storage cleaner safely identifies junk files without touching your personal data.
How much space will deleting temp files free on Chromebook?
Varies significantly — anywhere from a few hundred MB to several GB depending on how long since the last cleanup and how heavily the device is used. Active development machines and gaming PCs accumulate much more temp data than light-use devices.
Why do temp files come back so quickly after I delete them on Chromebook?
Temporary files are a normal side effect of using apps — browsers, editors, and the OS constantly generate them during normal operation. Deleting them is not a permanent fix; it's routine maintenance. They are harmless unless they grow very large or become corrupted.
What is the difference between temp files and junk files on Chromebook?
Temporary files are created intentionally by apps for active tasks. Junk files is a broader informal term covering temp files, leftover installer packages, duplicate downloads, and orphaned app data. Both are safe to remove via the built-in Storage Sense or Disk Cleanup tools.
