- Go to Windows Explorer, and create a folder/directory named
%systemdrive%
,%windir%
, or any other existing variable. - Open a command prompt, and go to the folder you just created.
You can't, because there are percent (%
) symbols in the folder name, confusing the command prompt, because the percent symbol is used for existing variables.
Escaping the percent (%
) symbol with two percent symbols (%%
) does not work, so DavidPostill's answer is wrong:
So, in Windows Explorer, why can we create a folder or file with the percent (%
) symbol, if the percent symbol is used for existing variables?
