var  str1 : string;begin  str1 := GetAppConfigDir( true );  ShowMessage( Str1 );  // note: for Fred.exe returns C:\ProgramData\Fred\  if not DirectoryExists(Str1) then    // Create Directory Str1    // call to 'mkdir' ??? what about on Linux??? and other platforms?
What is the cross-platform way for me to create the directory in Str1 (as returned by GetAppConfigDir) ?
I would assume that I need to ShellExecute a command for 'mkdir' for Windows, correct? How about for Linux and Macs, etc?
I found this page:

But I have to admit that I was totally lost in what it was trying to explain. 
An example, please?
