On Windows is there an interface for Copying Folders?
提问by Elmi Ahmadov
I want to copy folder A and paste to desktop.
我想复制文件夹 A 并粘贴到桌面。
I am currently using C++ so preferably an OO interface if available.
我目前正在使用 C++，所以最好使用 OO 接口（如果可用）。
采纳答案by Elmi Ahmadov
it works
有用
#include <iostream>
int main()
{
system("xcopy C:\Users\Elmi\Desktop\AAAAAA\ C:\Users\Elmi\Desktop\b\ /e /i /h");
return 0;
}

On Windows (Win32), you could use SHFileOperation, eg:
在 Windows (Win32) 上，您可以使用SHFileOperation，例如：
SHFILEOPSTRUCT s = { 0 };
s.hwnd = m_hWnd;
s.wFunc = FO_COPY;
s.fFlags = FOF_SILENT;
s.pTo = "C:\target folderbool CopyDirTo( const wstring& source_folder, const wstring& target_folder )
{
wstring new_sf = source_folder + L"\*";
WCHAR sf[MAX_PATH+1];
WCHAR tf[MAX_PATH+1];
wcscpy_s(sf, MAX_PATH, new_sf.c_str());
wcscpy_s(tf, MAX_PATH, target_folder.c_str());
sf[lstrlenW(sf)+1] = 0;
tf[lstrlenW(tf)+1] = 0;
SHFILEOPSTRUCTW s = { 0 };
s.wFunc = FO_COPY;
s.pTo = tf;
s.pFrom = sf;
s.fFlags = FOF_SILENT | FOF_NOCONFIRMMKDIR | FOF_NOCONFIRMATION | FOF_NOERRORUI | FOF_NO_UI;
int res = SHFileOperationW( &s );
return res == 0;
}
";
s.pFrom = "C:\source folder\*#include <exception>
#include <experimental/filesystem> // C++-standard filesystem header file in VS15, VS17.
#include <iostream>
namespace fs = std::experimental::filesystem; // experimental for VS15, VS17.
/*! Copies all contents of path/to/source/directory to path/to/target/directory.
*/
int main()
{
fs::path source = "path/to/source/directory";
fs::path targetParent = "path/to/target";
auto target = targetParent / source.filename(); // source.filename() returns "directory".
try // If you want to avoid exception handling then use the error code overload of the following functions.
{
fs::create_directories(target); // Recursively create target directory if not existing.
fs::copy(source, target, fs::copy_options::recursive);
}
catch (std::exception& e) // Not using fs::filesystem_error since std::bad_alloc can throw too.
{
std::cout << e.what();
}
}
";
SHFileOperation(&s);

Use this
用这个
// String buffer for holding the path.
TCHAR strPath[ MAX_PATH ];
// Get the special folder path.
SHGetSpecialFolderPath(
0, // Hwnd
strPath, // String buffer.
CSIDL_DESKTOPDIRECTORY, // CSLID of folder
FALSE ); // Create if doesn't exists?

Starting with Visual Studio 2015 you can use std::filesystem::copywhich is even platform independent since it is available in implementations supporting >= C++17.
从 Visual Studio 2015 开始，您std::filesystem::copy甚至可以使用独立于平台的版本，因为它可用于支持 >= C++17 的实现。
#import <stdlib.h>
int main(int argc, char *argv[]) {
system("robocopy \"C:\my\folder\" \"%userprofile%\desktop\\" /MIR");
return 0;
}
Change the behaviour of fs::copywith std::filesystem::copy_options. I've used std::filesystem::path::filenameto retrieve the source directory name without having to type it manually.
改变fs::copywith的行为std::filesystem::copy_options。我习惯于std::filesystem::path::filename检索源目录名称，而无需手动键入。

(assuming Windows)
（假设 Windows）
Use can use ShFileOperation (or IFileOperation::CopyItem on Vista). Max.
使用可以使用 ShFileOperation（或在 Vista 上使用 IFileOperation::CopyItem）。最大限度。

For a platform agnostic solution, I'd suggest Boost::filesystem. That link is basically the reference material. There is a copy_filemethod that copies a file from one location to another.
对于平台无关的解决方案，我建议使用Boost::filesystem。该链接基本上是参考资料。有一种copy_file方法可以将文件从一个位置复制到另一个位置。
On Windows, the desktop is a special folder:
