delete temporary internet files

Browsing the internet generates a lot of temporary files and caches on your computer. Over time, these accumulated temporary internet files can slow down your PC and take up significant disk space. Clearing your browser’s cache and deleting temporary files regularly is important for maintaining optimal system performance.

In this comprehensive guide, you’ll learn how to completely remove all temporary internet files in Windows.

What Are Temporary Internet Files?

When you visit websites, your browser stores copies of web page content, images, videos, and other media on your hard drive in a cache folder. This allows pages to load faster on repeat visits since some assets are already stored locally.

Here are some common temporary internet file types that build up over time:

  • Browser cache – Web page content, images, CSS, and JS files cached by Chrome, Firefox, etc.
  • Cookies – Small text files for login, settings, and site preferences.
  • Browsing history – Record of sites visited and searches.
  • Download history – List of files downloaded from the web.
  • Form auto-fill data – Saved usernames, passwords, and form field info.
  • Site data – LocalStorage, IndexedDB databases, and other site data.
  • Extension data – Cached info from browser extensions.

Browser caches and cookies are helpful for faster browsing. However, over time too many temp files accumulate and end up wasting disk space and slowing down your system.

Why Delete Temporary Internet Files?

Here are some key reasons you should periodically clear out temporary internet files:

  • Regain disk space – Temp files can occupy many GBs of disk space over time. Deleting them frees up space.
  • Protect privacy – Cache and history contains a record of your browsing activity. Clearing it increases privacy.
  • Fix browser issues – If browser is acting slow or buggy, deleting cache/temp files often helps.
  • Remove malware – Malware may secretly store files in caches and temporary internet folders.
  • Improve performance – Too many temp files cause clutter and slowdowns. Cleaning them speeds up Windows.
  • Prevent data recovery – Delete downloads, cached files, and temp data so it can’t be recovered later from the hard drive.

Make it a habit to clear temporary internet files, cookies, and browser caches regularly to get these benefits.

The files in these folders may be left over from installing programs, running apps, and other Windows operations.
