ExtractFilePath is a function in C++ Builder that is used to extract the directory path from a given file path.

Syntax:

AnsiString ExtractFilePath(const AnsiString& path);

Parameters:

• path: The input file path from which the directory path needs to be extracted.

Return Value:

• The directory path extracted from the input file path.

Example:

#include <vcl.h>
#pragma hdrstop
#include "Unit1.h"
#include <System.IOUtils.hpp>
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
void __fastcall TForm1::Button1Click(TObject *Sender)
{
AnsiString filePath = "C:\\Program Files\\MyApp\\data\\file.txt";
AnsiString directoryPath = ExtractFilePath(filePath);
ShowMessage(directoryPath);
}

In the above example, the ExtractFilePath function is used to extract the directory path “C:\Program Files\MyApp\data\” from the file path “C:\Program Files\MyApp\data\file.txt”. The extracted directory path is then displayed using the ShowMessage function.
