When it comes to win7/win8.1 redundancy, you have to mention this WinSxS special folder. This folder is located in the C:windows directory path, which stores a large number of system system backup, update patch backup. Over time, WinSxS also becomes the largest folder on the system disk.
For ordinary users, the most concern is the WinSxS folder why continue to grow? In fact, the WinSxS folder features a component store that stores the features of Windows important components, such as the familiar C:windowssystem32 directory.
The WinSxS folder itself creates a hard link with the C:windowssystem32 directory, so it is difficult to see the actual size directly in the explorer, as shown in the following figure:
So how do we look at the actual size of this folder? At this time, we directly use the Win7, Win8.1 built-in DISM management tools, query folder size, the specific operations refer to the following-
1, for example, Win8.1 platform, we right-click the Start button, select a command prompt (admin); Win7 Platform Click Start menu, enter CMD in the search box, then right-click to run as Administrator;
2. At the open command prompt, enter the following query command:
Dism.exe/online/cleanup-image/analyzecomponentstore
Querying the actual size of the current WinSxS folder
It is easy to see from the above picture that the WinSxS folder is actually smaller than the Windows Explorer data display.
In the WinSxS folder, there are three main components: 1, shared with Windows, 2, backup and disabled features, 3, cache, and temporary data.
