On the path C:\Users\your system name\AppData\LocalLow\Cygames\Shadowverse, are 10 gb of Shadowverse files. I wanted to move them on D drive, but how to make the game work after this? Symlink will make the game to think, that moved files on D drive, are still in old place on C drive.

1) Create anywhere on D drive a new folder, where you would want to move 10 gb of Shadowverse files from C drive (or use already created folder). I created folder shadowverse1 on the path D:\game\Steam\steamapps\common\Shadowverse.
2) Ctrl+x, Ctrl-v - cut, paste files from C drive to new folder on D drive (from C:\Users\your system name\AppData\LocalLow\Cygames\Shadowverse to, in my case, D:\game\Steam\steamapps\ common\Shadowverse\shadowverse1).
3) Delete folder Shadowverse from C:\Users\your system name\AppData\LocalLow\Cygames\ , which after cut-paste operation, must be empty. This is need, because on the step 5, we will create an illusion-folder Shadowverse and it would be impossible, if on this path would already exist a real folder with same name.
4) Open Command Prompt window as a administrator. If you do it right then the on Command prompt, the first line would be C:\Windows\system32> , not C:\Users\your system name> .
5) We have our files on D drive, but the game want to see them on C drive, so, we would create and illusion-folder (folder with labels to D drive) there. Bassicaly we didn't change anything from the game perspective, just added 1 more step (folder) in their file search. For creating illusion-folder on C drive with link to the files on D drive we would use symlink. For this we need to write in Command prompt next line:

mklink /J "C:\Users\your system name\AppData\LocalLow\Cygames\Shadowverse" "path for folder with files"

mklink - is the command for creating symlink
/J - represent the type of symlink which we want to create and it's mean directory junction.
C:\Users\your system name\AppData\LocalLow\Cygames\Shadowverse - is the path for new illusion-folder on C drive, which will create mklink command.
path for folder with files - is the path on D drive where we moved 10 gb of game files (D:\game\ Steam\steamapps\common\Shadowverse\shadowverse1).
In my case this line in the Command prompt was:

mklink /J C:\Users\your system name\AppData\LocalLow\Cygames\Shadowverse D:\game\ Steam\steamapps\common\Shadowverse\shadowverse1

6) Press Enter button.

That's all. Information of how to use symlink i taked from this site, which was on the first page of search.
