PCCare searches all locations under the Windows operating system where temporary files may reside. Although these are different on different PCs, PCCare searches them all. PCCare also looks for folders and files stored by different Internet browsers. Each of these browsers may store multiple temporary folders and files in different locations. PCCare can clean all of them. As a result, PCCare may find hundreds of old or unused Internet folders and files that may be slowing down your Internet performance.
Even though you may only use one internet browser under one operating system, PCCare searches for cache and temporary files for three different browsers (MS Internet Explorer, Netscape 7.x and Mozilla FireFox 1.0) on all the possible storage paths for multiple Windows operating systems (Windows 9x, Windows ME, Windows NT, Windows 2000 and Windows XP). PCCare will report that it cannot find a path or files for things that do not exist, even though it has found and deleted all your cache.
When PCCare has launched Defragment Hard Drive, it restructures and organizes how free and occupied space is used across your entire drive - this also results in a large quantity of activity on the drive which is shown in the "detail" listing. You will see both "Analysis" or before and a "Defrag" or after detailed report in the details section.
Running Defragment Hard Drive regularly should result in faster disk access times, yielding improved performance.
