cmd - Where does windows cls.exe reside? -

as know windows cmd can clear scren cls.exe command. cannot find command location.

usually, can use which find location of command program file. cls.exe, not work, , displays as:

which: no cls in c:\windows\system32... 

could guys me how cmd works? searched on internet, finding clues on how use it. not how works!

it's built-in command cmd.exe , not stand-alone program.

i.e. cls.exe not exist:

c:\>"cls.exe" '"cls.exe"' not recognized internal or external command, operable program or batch file.  c:\>"cls.com" '"cls.com"' not recognized internal or external command, operable program or batch file.  c:\>"find.exe" find: parameter format not correct 

the last one, find.exe, there show happens when exists.
