use system.IOUtils

TPath.GetPicturesPath;
       tpath.GetTempPath;
       TPath.GetMusicPath;
       TPath.GetPicturesPath;
       TPath.GetDocumentsPath;
       TPath.GetDownloadsPath;
       TPath.GetCameraPath;

TPath.GetFullPath( ');

system.IOUtils.TPath.GetDocumentsPath；

System.IOUtils.TFile.Copy

TFile.Create('');
  TDirectory.CreateDirectory('');

GetSharedDocumentsPath

PathDelim

TPath.DirectorySeparatorChar

 连接路径字符串

TPath.Combine(System.IOUtils.TPath.GetDocumentsPath, afileName)

c++builder 获取Android路径，可以直接用命名空间::写代码

包含头文件#include <System.Ioutils.hpp>

Caption= System::Ioutils::TPath::GetDocumentsPath();

"D:\\Users\\Administrator\\Documents"

System::Ioutils::TFile::Exists

得到文件清单,文件列表

ListBox1->Items->AddStrings( System::Ioutils::TDirectory::GetFiles(Edit1->Text));

递归文件清单

 TStringDynArray sl;
 sl =TDirectory.GetFiles(path, '*.txt', TSearchOption.soAllDirectories);

windows path ：

C:\Users\Administrator\Pictures
C:\Users\Administrator\AppData\Local\Temp\
C:\Users\Administrator\Music

System.IOUtils.TFile.Exists

System::Ioutils::TPath::GetDirectoryName //取路径

相当于以前的ExtractFilePath

一句话读文本文件

TStringDynArray fileArr=  System::Ioutils::TFile::ReadAllLines(filePath);

for (lineno = 0; lineno < fileArr.Length; lineno++)
         {
　　　　 fileArr[lineno]；

　　 }
