Cache files are absolutely necessary to provide you faster user experience. But there are times when you need to remove the cache, especially when you have trouble loading a new/updated version of a webpage or if you are short on storage space or RAM.

Deleting the cache files can improve your PC’s performance too, especially when it frees RAM and storage space significantly. This is also one of the reasons your PC needs a periodic restart as that resets the system cache appropriately.

But worry not, because cache files on your system are fairly easy to delete. This article will guide you through the various types of caches that exist on your system and how you can remove them. So, without further ado, let’s get started.

What is cache?

A cache (pronounced ka·shay) is a specialized high-speed hardware or software component that stores frequently requested data and instructions that in turn can be used for faster loading of websites, apps, services, and other parts of your system. Cache makes the most frequently accessed data readily available. 

Cache files are different from Cache memory. Cache files refer to frequently needed files like PNGs, icons, logos, shaders, and more that can be needed in multiple programs. These files are stored on your physical drive space and are usually hidden.

Cache memory on the other hand is a faster type of memory than your main memory and or RAM. It reduces the data access time tremendously, as it is located closer to your CPU when compared to your RAM and is much faster. Cache memory helps speed up the calculations of your processor which in turn makes your PC faster.

Cache memory is a relatively small storage type and is further graded into 3 levels:

  • Level 1 (L1): L1 is the smallest (usually between 8KB and 64KB) and the quickest cache.
  • Level 2 (L2) and Level 2 (L3): L2 and L3 are larger and slower caches when compared to L1.

You can view cache sizes on your system from the Windows Task Manager.

Why should you clear cache on Windows 11

  • Caches can be corrupted: Corrupted cache files can cause an app or your system to behave badly, or even crash in the worst cases. Hence, removing these corrupted cache files is recommended before you resume using your PC.
  • Clear storage space: While cache files are typically small in size, the accumulation of a large number of these files over a significant period of time can take up more free space on your system than you would expect. The solution is to remove this large chunk of cache files and recover the free space on your device.
  • Performance: The growing size of your cache files can directly impact the overall performance of your system. Cache storage getting filled more than it should can cause your system to run slower than you would typically expect.
  • Outdated information: Sometimes older cache files can prevent you from accessing the latest version of apps or websites on your system. You can fix this by clearing your cache files. 

Is clearing cache safe?

Clearing cache is safe. This is because clearing cache is not a permanent solution if you plan on revisiting the apps or websites concerned. At some point, these websites and apps will re-cache data on your system again.

Regardless, cache stores non-essential files, and deleting these files will not impact the general functioning of the apps or websites concerned. It will, however, impact how quickly these apps or websites load. To be clear, these load times will reduce once the app or website recreates caches on your system again.

Flush the DNS [get rid of DNS cache poisoning]

The Domain Name System (DNS) is like a phonebook for the websites you visit on your computer. Specifically, DNS translates domain names (for example, www.google.com) to IP addresses (8.8.8.8).

While the DNS cache allows your computer to load websites readily, it is possible that with time the number of these cache files has grown large. In worse cases, you can also encounter DNS cache poisoning, an event where a malicious agent has attacked and altered these stored IP addresses. In such cases, it makes sense to flush the DNS. So, let’s see how you can do it.

Press the Windows key on your keyboard to open the start menu.

In the start menu, search for ‘cmd’ and click on the same once it shows up in your search results.

In Command Prompt, type the following command, press Enter on your keyboard once you are done.

ipconfig /flushdns

The DNS cache has now been cleared.

Clear Microsoft Store’s Cache

Similar to other apps on your system, Microsoft Store also stores cached data on your PC and additionally, allows you to delete these files using the wssreset.exe file. This can help you in case you are having purchase issues, download issues, or an issue where Store apps simply won’t load. Use the steps below to help you clear your Microsoft Store cache.

Press Windows + R on your keyboard to open the Run command window.

Type in ‘wsreset.exe’ and press ‘Enter’ on your keyboard.

The wsreset.exe file will clear the Microsoft cache without asking you for any permissions and then close automatically.

Clear web browser cache 

Web browsers store ‘static assets’ of the web pages you visit frequently on your PC so you can access these websites faster on subsequent visits. Precisely, ‘static assets’ are assets of a website that remain more or less the same on each visit.

However, it is possible that the version of cached data of a website stored on your PC is an outdated one. This can further lead to issues every time you try to access this specific website. In that case, clearing your browser cache can be the perfect fix.

Let’s see how you can clear the cache on 2 of the most popular web browsers used on PC: ‘Google Chrome’ and ‘Mozilla Firefox’.

Google Chrome

Open Google Chrome on your PC and press Ctrl + Shift + Delete on your keyboard. This will open the Clear browsing data settings.

Click on ‘Time range’ and select the time range you want to delete Google Chrome’s cache for.

Scroll down and make sure only the ‘Cached images and files’ checkbox is checked.

Click on ‘Clear data’.

Your Google Chrome cache is now deleted.

Mozilla Firefox

Open ‘Firefox’ from your PC and press Ctrl + Shift + Delete on your keyboard. This will open the Clear Recent History settings.

Click on the ‘Time range to clear’ option and select the time range you want to delete your Firefox browser’s cache for.

Make sure that only the ‘Cache’ checkbox is selected.

Click on ‘OK’.

And that’s how you can clear your browser cache on your PC!

FAQs

What is the difference between cache and cookies on a web browser?

A browser cache saves information like pictures, files, and HTML data for a specific website so the same website can be loaded faster on subsequent visits.

Cookies, however, are used to store relatively small pieces of data, for example, user names, emails, sign-in data, shopping cart data, etc.

What is the file type of a cache file?

On most web browsers, the .cache extension is used to store the cached data. While this extension is not exactly a file format, it does, however, tell the user about the primary function of the file.

How can I open a cache file?

In order to open a cache file, you need software that can open a Snac-1.3 VDA file. You can, however, also use online websites like fileproinfo to analyze a cache file and see the text stored inside it.

Is cache memory fast?

Yes. Cache memory is one of the, if not the fastest memory on a PC. It is even faster than the RAM.

This is because the cache is typically an extremely small physical storage that is located very close to the CPU. Thus, it takes a very small number of clock cycles (unit of time in the CPU) for data to transfer from the cache memory to the CPU.

What happens after I delete cache on a web browser?

After you delete cache from a web browser, you will notice that some settings on specific websites have been deleted. Some websites will also load slower.

However, with time, as you visit these websites again, the web browser will create the required cache files again.
