It's not bad to clear your cached data now and then. Some refer to this data as “junk files,” meaning it just sits and piles up on your device. Clearing the cache helps keep things clean, but don't rely on it as a solid method for making new space.

Enter the URL of the website in the Google Cache Checker below to search Google Cache. Click on Search Google Cache, and it will redirect you to Google's cache of your cached website. The timestamp on caches will tell you when Google indexed your website last.

Your emails and contacts are safe when you clear the cache in Outlook. Deleting the cache really just forces Outlook to pull new information from online instead of from your hard drive. Additional files will be cached again after you erase the existing files.

On modern versions of Android, you need to delete the cache files for each app individually; there's no system-wide option to clear all cache. Note that you rarely need to delete all cache across your device. In most cases, clearing the cache from a few problematic apps can resolve storage or performance issues.
