Inno Setup - Constant for 'ProgramData' directory?

Question

I want my setup program to copy some files into the Windows ProgramData directory, I see that most Windows directories have pre-defined constants already defined in

Answer 1

It's the {commonappdata} constant.

It's named so, because historically (Windows XP) the path used to be C:\Documents and Settings\All Users\Application Data (now that's a symbolic link to the C:\ProgramData).

And for the same reason, using the {sd}\ProgramData is not the correct way.
