The best way to deal with it is to expand the capacity of drive C, reinstall the system, and then the software will bump into other drives.
If you want to lose weight, it is recommended to use the Rubik's Cube Assistant, which has a disk cleaning plug-in. Just use his system disk slimming function. In terms of software, you can use the 360 software mobile plug-in to transfer the software to other disks. Because this software is old, it may not support the new system and the moved software very well. Moving important software to other disks is not recommended.
If you are familiar with computers, you can try to use command transfer software such as mklink.
