Iterate inside folders and copy subfolders only-CodePudding

I am working on a project and what I have to do is iterate inside some folders and copy only the subfolders of them and paste in in some different location.

Here's the folders structure:

-Folder1
--subfolder1
---test.doc
---test.pdf
---test.xlsx
--subfolder2
---test.mp3
---test.pdf
---test.eml

-Folder2
--subfolder4
---test2.pdf
---test2.msg
---test2.eml
--subfolder3
---test4.msg
---test4.eml
---test4.pdf

Now, what I want to do is "extract" the subfolders from their parents and copy to them to a different directory. In the end the structure has to be like this:

--subfolder1
--subfolder2
--subfolder3

(of course with their corresponding files inside them)

Here's what I have tried so far but it doesn't seem to do the exact thing that I want, it just copies all the folder how they appear in the target directory, with the parent folders too.

    static void CopyDirectory(string sourceDir, string destinationDir, bool recursive)
    {
        // Get information about the source directory
        var dir = new DirectoryInfo(sourceDir);

        // Check if the source directory exists
        if (!dir.Exists)
            throw new DirectoryNotFoundException($"Source directory not found: {dir.FullName}");

        // Cache directories before we start copying
        DirectoryInfo[] dirs = dir.GetDirectories();

        // Create the destination directory
        Directory.CreateDirectory(destinationDir);

        // Get the files in the source directory and copy to the destination directory
        foreach (FileInfo file in dir.GetFiles())
        {
            string targetFilePath = Path.Combine(destinationDir, file.Name);
            file.CopyTo(targetFilePath);
        }

        // If recursive and copying subdirectories, recursively call this method
        if (recursive)
        {
            foreach (DirectoryInfo subDir in dirs)
            {
                string newDestinationDir = Path.Combine(destinationDir, subDir.Name);
                CopyDirectory(subDir.FullName, newDestinationDir, true);
            }
        }
    }

Thank you in advance.

In recursive function you have to create another loop which iterates inside of subfilders and then you just copy the files inside the new directory. Basically like this:

 if (recursive)
            {
                foreach (DirectoryInfo subDir in dirs)
                {
                    DirectoryInfo[] Subdirs = subDir.GetDirectories(); 
                    foreach (DirectoryInfo subDir2 in Subdirs)
                    {
                        string newDestinationDir = Path.Combine(destinationDir, subDir2.Name);
                        CopyDirectory(subDir2.FullName, newDestinationDir, true);
                        Console.WriteLine("Finnished copying file: "   subDir2.Name);
                    }
                }
            }
