What is a computer cleanup and what is cleared?

Defragmenting is the cleanup of a hard disk, the computer's memory. This program will run faster! Windows just throws packets when saving to disk. This must be sought long to start the program. The defragmentation gives these packages together again! Says program run faster! Computer cleanup is only one best Registry Cleaner, where unnecessary data are deleted!

Ccleaner deletes e.g. Uninstall remains unused registry entries Trash content, Internet garbage. Sorted Defrag your hard drive and creates space on this. I think the great programs and have never had a problem with that. You can also disable startup programs that you do not need constant which frees memory and thus increases the speed of the computer. I personally find these programs better than the internal of Windows.

When the cleanup files for example during the installation of a program are stored only temporarily erased. They usually have the extension. Tmp (= temporary). This creates space on the hard disk. Besides, you should see the Windows Recycle Bin. Because files are entered in it, although the directories are no longer visible, but still exist on the computer yet. This also applies to files that have accumulated while surfing (temporary internet files). When files are written, they spread all over the Windows disk, and remembers where are the individual parts. When a plate is very full, small snacks in gaps between other files can be pushed (fragments). When you defragment the file fragments together, and written in consecutive blocks, so a program can read them more quickly. Some system files can not be defragmented, because it is constantly in Windows has access, and therefore may not be changed. Programs and games are not removed.
