What are CACHE files and how to open them

Are you having problems opening a CACHE file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CACHE files.

What is a CACHE file?

CACHE files have multiple uses, and Cache is one of them. Read more about the other uses further down the page.

Cache File

The .cache file extension is used to store cache information for various Internet browsers. Sometimes, a CACHE file can be used to pull up an image of a cached website when the user's computer is not connected to the Internet. For example, when a user chooses to save a website using their Internet browser, the website page will then be cached on the user's computer, and the user will not have to access the Internet to access the information on that web page.

Other applications, such as image editing programs, also use the .cache file extension to speed up the loading times of recently-viewed application files.

You usually do not need to edit or view these files, as they only contain information usable by the software program that uses them.
