How could I set every folder inside of a folder to case sensitive in Windows 10?

My initial thought was:
“Ah yes! This is gonna be simple! To not corrupt my folders and their contents up (Which I feel like that would happen if I used fsutil.exe on a folder with stuff inside.), I will take everything out, and then run — fsutil.exe file setCaseSensitiveInfo “C:My Stuff” enable — On my folder then move everything back on!”
Though it wasn’t as simple…Unfortunately, because all that did was make the “My Stuff” Folder have case sensitivity but the others not. So how could I set every folder inside of my folder to a case sensitive folder, without corrupting everything up? (Because I fear that it could very easily delete or corrupt everything in there, I mean, it’s good precaution isn’t it?) And also, this was performed on a Windows 10 Pro 10.0.19045 Compilation 19045. (If that’s important info of course.)
