windows native copy multple file dialoge

How to copy or move MULTIPLE files and show respective native file dialog ? like this:

Although I can copy multiple files using this code:

using Microsoft.VisualBasic.FileIO;
...
FileSystem.CopyFile("1.txt", "2.txt");
FileSystem.CopyFile("3.txt", "4.txt");
...

But it shows separately for each of files like:

I know there's already FileSystem.CopyDirectory(...). But I don't want to copy whole directory. I just want some files from directory to be copied without multiple prompts or separate progress.

I believe its possible. Because I seen that in team viewer and anydesk software.

Expanding on my earlier comment, we will need to invoke IFileOperation through COM - so it's going to be a little dirty with the hooking and marshalling.

For reference, there is an archived MSDN article from 2007 that explains the whole thing step-by-step: "IFileOperation in Windows Vista" by Steven Toub.

The author of PictureManager has nicely wrapped them in a pretty clean implementation. They have kindly licensed the whole project as CC0. This'll save us from having to collect all the Shell P/Invoke code ourselves.

1. Grab the ShellStuff folder from the PictureManager repo.

2. Delete the FileInformation.cs and PicFileOperationProgressSink.cs.
   They're specific to the app and we won't need them.

3. Edit your .csproj file, and add the following:

<Project ...>
  ...
  <!-- Add this whole ItemGroup: -->
  <ItemGroup>
    <COMReference Include="Shell32">
      <WrapperTool>tlbimp</WrapperTool>
      <VersionMinor>0</VersionMinor>
      <VersionMajor>1</VersionMajor>
      <Guid>50a7e9b0-70ef-11d1-b75a-00a0c90564fe</Guid>
      <Lcid>0</Lcid>
      <Isolated>false</Isolated>
      <EmbedInteropTypes>true</EmbedInteropTypes>
    </COMReference>
  </ItemGroup>
  <!-- End add -->
</Project>

4. Now use it in your code like so:

using var fo = new FileOperation();

// There's a whole bunch of flags, all of them well commented.
fo.SetOperationFlags(FileOperationFlags.FOF_NOCONFIRMMKDIR);

// Define the files you'd like to copy:
fo.CopyItem(@"C:\somewhere\old1.zip", @"C:\elsewhere\", @"new1.zip");
fo.CopyItem(@"C:\somewhere\old2.zip", @"C:\elsewhere\", @"new2.zip");
// ...etc

// Do them all in one go:
fo.PerformOperations();

You should see the native dialog performing the copy operations. Including the native confirmation dialog if files with the specified names already exist in the destination.
