How to view Win8.1 WinSxS folder actual size

Speaking of 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 creates a hard link with the C:\\Windows\\system32 directory. Therefore, it is difficult for us to directly view the actual size in the resource manager. Refer to the following figure:

Then we How to check the actual size of this folder? At this time, we directly use the built-in DISM management tool of Win7 and Win8.1 to query the folder size. For details, refer to the following ——

1. For example, Win8. 1 platform, we right click on the start button, select command prompt (admin); Win7 platform click on the start menu, enter cmd in the search box, then right click to run as administrator;

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

Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore

//Query the actual size of the current WinSxS folder

From above It is easy to see in the picture 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.
