How to view the actual size of Win8.1 WinSxS folder

When it comes to Win7/Win8.1 redundancy, I 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 backups and update patch backups. Over time, WinSxS has also become the largest folder for system disks.

For ordinary users, the main concern is why the WinSxS folder continues to grow bigger? In fact, the specific function of the WinSxS folder is component storage, which stores important Windows component functions, such as the familiar C: Windows system32 directory.

The WinSxS folder itself and the C:Windowssystem32 directory create a hard link, so it is difficult to directly view the actual size in the resource manager, refer to the following figure:

Then how do we view this The actual size of the folder? At this time, we directly use the built-in DISM management tool of Win7 and Win8.1 to query the folder size. The specific operation is as follows: ——

1. For example, Win8.1 platform, We right click on the Start button, select Command Prompt (Administrator); Win7 platform click on the Start menu, enter cmd in the search box, then right click to run as administrator;

2, in the open command prompt Enter the following query command:

Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore

//Query the current WinSxS folder actual size

From the above picture It is difficult to see that the actual capacity of the WinSxS folder is lower than the data display of Windows Explorer.

In the WinSxS folder, it consists of three main parts: 1. Shared with Windows; 2. Backup and disabled functions; 3. Cache and temporary data.
