In addition, the files of the previous version will be saved after upgrading to Windows 10, which will take up a lot of space. If the disk for saving backup files gets full, it will be hard to create backup data any more which is not good to manage data and operating systems. So it is necessary to clean up the backup files. And releasing a lot of space can make the operating system run smoothly.
