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.
