What does clearing cache?

Answered by Phillip Nicastro

Clearing cache refers to the process of deleting temporary files stored on your device by apps and web browsers. These files are typically created to improve the performance and speed of your device when using these apps and browsing the internet. While cache files can be useful in speeding up your experience, they can also accumulate over time and take up unnecessary storage space.

When you use an app or visit a website, your device stores certain data, such as images, scripts, and other files, in its cache. This allows the app or website to load more quickly the next time you access it, as it can retrieve some of the data from the cache instead of downloading it again from the internet. This caching mechanism helps to reduce data usage and improve loading times.

However, as you continue to use different apps and browse various websites, the cache files can gradually build up and become outdated or redundant. This can lead to several issues, including:

1. Storage Space: Cache files can take up a significant amount of storage space on your device, especially if you have been using it for a long time without clearing the cache. By clearing the cache, you can free up some storage space and potentially improve the overall performance of your device.

2. Website Behavior: Sometimes, clearing the cache can resolve issues with the behavior of certain websites. If you notice that a website is not loading properly, displaying outdated information, or experiencing other glitches, clearing the cache can often address these problems. By deleting the stored cache files, your device will be forced to download fresh data from the website, potentially resolving any issues caused by outdated or corrupted cache files.

3. App Performance: In some cases, apps may start to slow down or become unresponsive due to excessive cache files. Clearing the cache can help improve the performance of these apps by removing any unnecessary or outdated files that may be causing the slowdown.

Now, let’s look at how to clear the cache on different devices and applications:
