I believe everyone is already very familiar with Windows. We use it every day, but how much do you really know about the system directories in Windows? This article will give a detailed introduction to the system directories in Win9x, WinME, and Win2000, including their functions and simple applications.
The so-called system directories are the directories where the main files of the operating system are stored. The files in these directories directly affect whether the system can work normally. Understanding the functions of these directories will surely be a great help in using the system better. Unless otherwise noted, the directories introduced below are located in the Windows directory under Win9x/ME, and in the Winnt directory under Win2000.
All Users folder:
『Win9x/ME』All Users folder. It includes the desktop files and Start menu contents used by the system's default logon.
『Win2000』There is no such folder in the Win2000 system directory. Win2000 places user information in the Documents and Settings folder under the root directory, with one directory for each user, including the Start menu, desktop, Favorites, My Documents, and so on.
Application Data folder:
『Win9x/ME』Application data folder. It includes things such as shortcuts on the taskbar and some input method files. Depending on the different software used on your system, the contents of this directory will also differ.
『Win2000』In the Documents and Settings folder, each user has a corresponding Application Data folder. Likewise, because each user uses different software, the contents of the directory also vary.
Applog folder:
『Win9x/ME』Application log file directory. Log files are used to record information such as the files an application needs to call while running and the addresses it uses. To view these files, just open them with Notepad.
Catroot folder:
『Win9x』Computer startup test information directory. Most of the files included in this directory are hardware and software information detected when the computer starts up.

History folder:
『Win9x/ME』History folder. IE has a function that can record the URLs the user has visited, and this directory is used to store those URLs.
『Win2000』Each user's history files are independent of each other. They are located in the Local Settings directory inside each user's directory under the Documents and Settings folder.

System folder:
『Win9x/ME/2000』System folder. Important files in the system are stored in this directory, and when installing new software, files are also copied into this directory. Since many files here are shared by multiple programs, if you are prompted to delete files in this directory when uninstalling software, it is best to choose not to delete them.

『Win2000』Each user has a Temporary Internet Files folder, located in the Local Settings directory inside each user's directory under the Documents and Settings folder.
Web folder:
『Win9x/ME/2000』The files in this folder are mainly some hypertext templates, channel icons and images, and so on. The layout of some windows in Windows is also completed through the files here.

Since the files in the system directories are all very important, you must be especially careful when making changes. If you are not very familiar with the system, I suggest you had better leave them alone.
