How to get less system space after upgrading WIN10 system

In fact, C disk space is mainly caused by the following directories we need to redefine the address of the directory can be resolved, as follows.

Drive backup Folder C:\windows\system32\DriverStore\FileRepository
System backup folder C:\windows\winsxs\Backup
Setup Backup folder C:\windows\installer

The solution is as follows

1. We create a BAK catalogue in our own computer-not-system disk, this name casually called in this article small set to in: D Disk A new directory named Bak for storing these files;

2, the directory is created we now start the menu "right", select "Command Prompt (Administrator)" as shown in the following figure;

3, then we enter Mklink to see how it is used;

4, input commands to add links;

Directory original directory linked to mklink/j D:\bak\Backup C:\windows\winsxs\Backup mklink/j D:\bak\installer C:\windows\installer mklink/j D:\bak\FileRepository C:\Windows\System32\DriverStore\FileRepository

5, copy the original system files to the new directory, and then delete the contents of the original directory.

All right, so we'll put the C-disk above the number of directory files deleted after the C disk space has, the future data will automatically back up to our set of D disk OH.
