Why some programs have to be installed on the C drive

This is because, for example, like 360 and other software that is helpful to the system, it is more convenient to deal with your own things in the C disk, and you can find the files of the system more quickly and accurately, as well as, for example, some small software in QQ, you have to use it for a long time, and it will be faster to install it in the C disk, and it is more convenient to find his information when updating the software, so as to effectively remind you to update. In fact, a lot of software you don't install on the C drive, in fact, some files will still default to the C drive, and some startup project files will also hit the C drive, which is why some software even if it does not hit the C drive, but after reinstalling the system, it will still not be used (can't be opened).

This is someone else's power,General software will read some of its data or start the supporting file after starting,And the programmer of this kind of program in the design for convenience,Has been designated in the C disk,If you want to use this software, of course, you have to do what it says,Think about some software in order not to be pirated,You must also plug in the "dog" it sets。

If your system is installed on the C drive, the programs required to run the system are installed on the C drive, the drivers must also be installed on the system drive, and many applications also have to install some programs on the C drive, at least the shortcuts to the programs are built on the C drive. There's no why, the system was designed like this when it was designed, hehe.

Since the C disk is a system disk, it is also a boot disk. Therefore, it is impossible for the boot file and system file to leave here to run. Only one Windows system must be installed on the C drive, if there are two or more operating systems, then other Windows do not have to be installed on the C disk, that is to say, the main operating system must be installed on the C disk, and those QQ, Anyi, clothing, Office, etc. do not have to be installed on the C disk.

If it is installed on this C disk, it will cause the space of the C disk to become less and less, resulting in insufficient virtual memory (of course, there are computer hard disks that are large enough to not have this problem), and the running speed will be slow.

Because the C drive is a system disk, some things have to be placed there to work...

If the remaining capacity of the C drive is relatively large, then installing it on the C drive has little impact.

Suggestion: 1. Anti-virus software, firewall, office, etc. are recommended to be installed on the C drive (unless they are green version), because they are already embedded in the system and are integrated as part of the system. Even if you install them on a different disk, you have to write a lot of files such as dynamic link libraries to the C drive.

The effect is not much better than installing it on a C disk, in fact, it is equivalent to installing a part of the software on a C disk, and a part of it on other disks, which is better than a unified installation on a C disk.

2. Commonly used software (Winrar, Thunderbolt, etc.) is not installed in C disk, one is that these software are small, easy to install, and easy to obtain. Second, these software do not have much impact on the system, and almost no files are written to (or very little) the C drive, and the installation on the C drive will only occupy the system disk space.

If we install the software on a non-system disk, reinstall the system, or restore the backup system, the files in the destination location will become junk because these files are only a part of the whole software and cannot function properly. As you install newer versions of the software again and again, junk files will become more and more junk files, and it is very difficult to clean up, so I don't believe you can distinguish which files are useful and which are not in one software directory.

Some people like to use ghost software to back up their system, including some "one-click backup" tools, which will result in only a part of the software being backed up, and the files in the destination 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, and then add a mechanical hard disk to store data, which is obvious to improve the speed of the computer, because now the performance bottleneck of the computer is on the hard disk. In 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, and the word program reads the document from the hard disk, during which it will also involve the system function call, and the pressure of the whole process is given to the mechanical hard disk; If it is installed on the system disk, then at least the pressure of running the word program and the system function call is shared by the SSD, so the speed will naturally be improved a lot.
