ForceDirectories Method (System:SysUtils:ForceDirectories) is a SysUtils Method listed in Disk And Directory Support Routines that creates a new directory, including the creation of parent directories as needed. ForceDirectories creates a new directory as specified in Dir, which must be a fully-qualified pathname. If the directories given in the path do not yet exist, ForceDirectories attempts to create them.
In this post, you’ll learn how to use Force Directories Method, Syntax of ForceDirectories to create folders in c++ and its examples. By learning Force Directories Methods. it will help you to easily build C++ applications using the C++ IDE.

bool __fastcall ForceDirectories(System::UnicodeString Dir); |
ForceDirectories returns True if it successfully creates all necessary directories, False if it could not create a needed directory.
Note that, do not call ForceDirectories with an empty string. Doing so causes ForceDirectories to raise an exception. The Vcl.FileCtrl unit (Windows only) contains a ForceDirectories function that is deprecated. System.SysUtils.ForceDirectories is preferred, and can be used in multi-device applications.
Here is a simple example of using the ForceDirectories() Method in C++

#include <vcl.h> #pragma hdrstop #include "Create_Directory_Unit1.h" //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" TForm1 *Form1; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { ForceDirectories( L"D:\\MyFolder\\MySubFolder\\MyOtherSubFolder"); } |
This example above will create “MyFolder”, “MySubFolder” and “MyOtherSubFolder” directories together.
Here’s another example showing how to create folders or directories in C++
