Is the software installed on the C drive (system disk) or is it better?

Windows application software (Office, QQ, CAD, etc.), installed in the system disk, or non-system disk, this seems to be a more controversial topic. Let's not say which viewpoint is correct, but “set the truth and reason”. The so-called system disk, usually the C disk, that is, the installation location of the operating system, and not the system disk is of course the disk other than the C disk. For a long time...long time...in the past, the application software was “green”, the so-called green is copied from one directory to another, and after copying from one computer to another, it can still run. Use; and now the software, if not deployed by the installer, a simple copy can not be used. Because the current software has a lot more new than the past, such as COM components, after the software is installed, in addition to putting files in the target directory, it will also put files in the system32 and other directories, register component information in the registry. In this way, a piece of software is actually split into multiple places, and we can't just copy it. If we install the software on a non-system disk, reinstall the system, or restore the backup system, the files at the target location will become junk, because these files are only part of the entire software and will not work properly. With the installation of newer versions of the software over and over again, there will be more and more junk files, and it is very difficult to clean up. I don't believe you can distinguish which files are useful and useless in a software directory. Some people like to use the ghost software to back up the system, including some "one-click backup" tools, which will result in only backing up part of the software, and the files in the target location are not backed up. In order to improve the speed of the computer, some people like to configure a solid state drive as a system disk, plus a mechanical hard disk to store data, this is an obvious increase in the speed of the computer, because the performance of the computer is now on the hard disk. This kind of computer environment, if the software is installed on a non-system disk, when we open a document, such as a word document, the computer first runs the word program, the word program reads the document from the hard disk, and the system function call is involved. The pressure of the whole process is given to the mechanical hard disk; if it is installed in the system disk, then at least the word program and the system function call part of the pressure are shared by the solid state hard disk, so the speed naturally increases a lot. Bao Yun heard a saying: the mode of using solid state drive (system disk) + mechanical hard disk is only a fast boot speed. It is really impossible to understand what the theoretical basis is. Finally, it is recommended that windows7 and above systems have a system disk capacity of no less than 80G. This article comes from [System Home] www.xp85.com
