我想复制文件夹A并粘贴到桌面。
我目前正在使用C ++,因此最好是OO接口(如果可用)。
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 folder\0";
s.pFrom = "C:\\source folder\\*\0";
SHFileOperation(&s);
用这个
bool 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;
}
(假设是Windows)
使用可以使用ShFileOperation(或Vista上的IFileOperation :: CopyItem)。最大。
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。有一个copy_file
方法将文件从一个位置复制到另一个位置。
在Windows上,桌面是一个特殊文件夹:
// 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?
从Visual Studio 2015开始,您可以使用甚至独立于平台的std::filesystem::copy
,因为它在支持> = C ++ 17的实现中可用。
#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();
}
}
用fs::copy
改变std::filesystem::copy_options
的行为。我已经使用std::filesystem::path::filename
来检索源目录名称而无需手动输入。
有用
#include <iostream>
int main()
{
system("xcopy C:\\Users\\Elmi\\Desktop\\AAAAAA\ C:\\Users\\Elmi\\Desktop\\b\ /e /i /h");
return 0;
}
以下是使用SHFileOperation的示例:

这是一个没有它的快速黑客:
#import <stdlib.h>
int main(int argc, char *argv[]) {
system("robocopy \"C:\\my\\folder\" \"%userprofile%\\desktop\\\" /MIR");
return 0;
}
