FileName |
The file name from which the drive and directory are extracted. |
Note: GetDirectoryName raises an exception if the given file name contains invalid characters.
Example (Delphi):
WriteLn(TPath.GetDirectoryName('D:\Projects\HelloWorld.exe'));
Example (C++):
printf("%s \n", TPath::GetDirectoryName("D:\Projects\HelloWorld.exe"));
Note: The code output: "D:\Projects". The path name does not include the last delimiter.
Note: On Linux, GetDirectoryName is identical to ExtractFileDir.
