This should be the default, because the 360 folder of slimming transfer is on the E disk, so the default transfer can only be transferred to the disk or transferred to other disks. You can set up the 360 folder to slim down and transfer it to the D disk, and then try to slim down the computer to see if it will be transferred to the disk you need. This is a high-tech job. This is the same as moving a building in practice. You can install the 360 on the E drive. It is recommended to install anti-virus software on drive C, because this is the most active place.
