Copy files to the system32 batch in the Windows folder of C disk _dos/bat

Now I want to copy the ' FinalData.exe ', ' OfficeDiary.exe ', ' DisplayX.exe ' three programs to ' C:\WINDOWS\ ' from the "C:\Program files\ common green software \soft\" System32 ' and cover the original three, how should write???
Question 1: Does the compilation of batches support long folders and long filenames?
Question 2: Does the batch process support the Chinese folder?
Question 3: Is there a hint when overwriting the original file? If so, how can you let it not be prompted to cover it directly?
@echo off for%%a in (FinalData officediary displayx) do (copy/y "C:\Program files\ common Green software \soft\%%a.exe" "C:\WINDOWS\syst Em32 ") Pause copy multiple files from a Chinese folder to a specified long filename, how to write a batch

Copy three files from one folder on your desktop to the System32 folder in the C-Disk Windows folder
The three files in the "ERP database client file" on the desktop Dbnetlib.dll dbnmpntw.dll ntwdblib. DLL copied to the C disk Windows\System32 folder to overwrite the original three files.
I just need a batch, thank you.
1.
@echo off
ren%windir%\system32\dbnetlib.dll dbnetlib.old
ren%windir%\system32\dbnmpntw.dll dbnmpntw.old
ren%windir%\system32\ntwdblib. DLL Ntwdblib.old
cd/d "%userprofile%\ Desktop \erp Database client file"
copy/y Dbnetlib.dll%windir%\system32\
copy/y Dbnmpntw.dll%windir%\system32\
copy/y Ntwdblib. DLL%windir%\system32\
Exit
Rename the original file. Copy the file at the same time. If you do not want to keep the original file, Ren three lines will be deleted.

Every paragraph on the top is a line, so don't make it 2 when you copy it to bat.
