How can I copy and paste a file in Windows using C++?

c++, file, fstream, windows

Solution

If you are using the Win32 API then consider looking into the functions `CopyFile` or `CopyFileEx`.

You can use the first in a way similar to the following:

CopyFile( szFilePath.c_str(), szCopyPath.c_str(), FALSE );

This will copy the file found at the contents of `szFilePath` to the contents of `szCopyPath`, and will return `FALSE` if the copy was unsuccessful. To find out more about why the function failed you can use the `GetLastError()` function and then look up the error codes in the Microsoft Documentation.

Problem

I have googled this, but I am still confused about how to use it. I am making a file manager, and I want to be able t o copy and paste a file into a new directory. I know to copy I need to use `file.copy()`, but I am not sure how to implement it into my code. I would like to do this using fstream.
