As you view webpages, files and pictures associated with those pages are stored in cache (Temporary Internet Files folder) on your computer. Internet cache speeds up the display of pages you frequently visit or have already seen because your browser can open them from your computer instead of from the web.
If you surf the Internet a lot and have enough space on your PC, you might want to increase the size of your cache (Temporary Internet Files folder) as increasing cache space can increase the speed of displaying of previously visited pages. But if you you increase cache size, it decreases the amount of space available for other files on your computer.
Depending on you needs you can easily choose how much space is set for cache (Temporary Internet files).
Note: Files stored in your cache take up space, so from time to time, you may want to clear out files stored in your cache to free up some space on your computer.
